Statistics: On Z-Tests and Sampling Distributions

As promised, this week Kyle T. presents the first of several foundational mathematical tests, used in statistics to compare populations and samples. This week’s test is the z-test and is the most basic analysis conductible in descriptive statistics. For those standardized-test takers of you out there, this test parallels the analyses that the testing companies conduct in order to calculate your scaled scores from your raw scores.

Next week: t-Tests!

Statistics: On Comprehending the Null Hypothesis

When last week Kyle presented Null-Hypothesis Statistical Testing, he emphasized that it’s essentially the basis of testing and analysis in the social sciences. With import like that, the null hypothesis itself certainly calls for clear explication; so, this week, in our excerpt from his seminar on foundational statistics, our tutor Kyle T. takes a closer look at the null hypothesis and, specifically, how exactly it operates as a standard in research.

Next week he’ll build on this conceptual understanding of the logic of testing by introducing the first of the actual mathematical tests conductible in social-scientific research.

Stay tuned, students!

Statistics: On Null-Hypothesis Statistical Testing

This week, Kyle T. expands the foundation of Statistics that he began laying down in his previous video; having established the background of the normal distribution and the purpose of inferential statistics, he today explains the fundamental test in social-scientific research: the null-hypothesis test.

Happy Daylight Savings, all!

The Timbre of College Visits

For those of you in high school, the next phase of your life likely means more than just a little concern; imminent major life-change – going to college – causes stress in even the best of students.  For your parents, helping you confront this stress – this transition from high-school student into a college freshman – likely means urging you to the essential rite of passage: the college visit.  If the mere idea of spending time with your parents — particularly when “time” means a car, where nothing but your trusty iPod earbuds separate you — pushes your stress-level into the red, then you are an ordinary teenager.  With nearly toxic hormone levels, you have a biological imperative to disobey your parents.  Regarding college-visits, however, your parents are only trying to give you a glimpse of utopia…and the longer you wait to go, the less likely you are to find that campus, the one that is perfect for you.

In fact, the biggest mistake that most teens make is waiting until the Summer to make these vital college visits.  Student life is the single most important characteristic of any campus.  Though your parents may still marvel at the architecture, the curriculum, and the student-to-faculty ratio (and you may be nothing but bored at these features of a school), you as a prospective student owe yourself the marvel at real college students in their natural habitat.  Simply put, college is more than school.  It will be your home; suburban or urban, small or large, college-based or university-based, it will become your community. And, as the traits and nuances of any community cannot be found on a bland website or in empty buildings, community must be experienced.

So, when you visit a school, don’t take just the standard campus tour.  Observe how the students there behave in class, act around campus, and – especially – commune in the dining hall (the belly of every community).  Take time to linger in each new environment and imagine yourself among its vibrant crowd.  Ideally a collegiate reverie will titillate your teenage soul, inspired into an urgent sense of optimism about making this daydream a reality; ideally you’ll know that that school – that that community – is meant for you. Alternatively, if you find yourself not daydreaming but dreading a certain undergraduate experience instead, then you will still have done yourself a favor; as you begin to plot your future, you’ll have the knowledge that that experience, or at least that that community, doesn’t ring true for you. You’ll even have plenty of time to prepare for a gap year . . . but that’s a matter for another article.

In the meantime, don’t hesitate to hit the college circuit and figure out the nuanced differences between the communities of Wellesley and Wesleyan, Williams and William and Mary, for yourself.

Statistics: On Measurement, the Normal Distribution, and the Two Types of Statistics

Greetings, stats. and social-sciences students!

We here at the blog apologize for missing our weekly installment last week, but hope to make it up to you this week with not just one but two substantial new videos from Kyle T.’s seminar! In these videos, Kyle discusses the various types of measurement and statistics that can be taken and performed, to describe and analyze data. He also explains the useful abstraction that is the Normal Distribution, a concept (as he equates) as fundamental to statistics as the concept of the circle is to geometry. Exciting stuff!

Next week: Null-Hypothesis Statistical Testing, the backbone of practically all social-scientific research-analyses. Stay tuned!

Yours,

Statistics: Introduction & Overview

Welcome, aspiring statisticians and social scientists! The Veritas Blog is happy to premiere its new series, geared entirely to you.

Tutor Kyle T., whom some of you may remember from our returning series on the GRE, today gives us all a brief overview of what this series will cover and how it will cover it. In short, this series will be a comprehensive and direct presentation of what statistics are and how and why they are used in the social sciences; thus, it is designed so that you may take from it a basic, working understanding of statistical tests and descriptors that you will then be able to apply to either generating your own research or considering and comprehending others’.

We hope that you’re as excited as we are! Stay tuned; next week we’ll dive right into the content.

Yours,

The Veritas Team

Admissions: In Summary

Wrapping up the Veritas College-Admissions series, co-founders Andrew M. and Jay B. underscore the key take-aways from their presentation, “How to Get into (Your) Harvard.” Relating the story of a past applicant, they remind us how getting into (your) Harvard is not about being involved in a million activities in high school, but rather finding what you love and pursuing excellence at it.

Intro. statistics and social-sciences students, stay tuned; next week, the Veritas Blog will premiere its new series on introductory statistics, geared for social-scientific research!

Happy Presidents’ Weekend, all!

Admissions: 12th Grade

High-school Seniors, the road to college-admissions is now much shorter than it used to be when you were in 9th, 10th, and 11th grades; having already accomplished yourselves verily through academics, extracurriculars, and other narrative-building experiences, it’s time now for you to put everything together, down on paper, and then send it off to all the colleges you choose: in other words, to your Harvards. In this penultimate post in the Veritas College-Admissions series, relating “How to Get into (Your) Harvard,” co-founders Jay B. and Andrew M. discuss the expectations, processes, and senses of accomplishment that characterize every successful high-school Senior’s year.

Admissions: 11th Grade

In our fifth installment into our College-Admissions series, Veritas co-founders Andrew M.and Jay B. discuss the important Junior Year, when most high-school students take their SATs, prepare for their college-applications, and make their college-visits.  For these students, it’s the “make or break” year, as Andrew says; and together with Jay, he explains how students can make the opportunity an accomplishment and the beginning of the core college-application process a smooth success.

On Asking the Students

A recent article by The New York Times calls into consideration the insights of public-schoolchildren into the effectiveness of their teachers. Citing an initiative sponsored by the Bill and Melinda Gates Foundation, the article discusses the recent practice of surveying these schoolchildren on matters like teacher productivity, attention to mistake-correction, and focus on student-preparation for standardized tests.  The survey-questionnaires, developed by Harvard‘s Ronald Ferguson, Ph. D., are then meant to provide bases of correlation with another measure of teacher effectiveness: added value, in terms of change in students’ scores on tests over each year. In this way, the researchers aim toward using the correlate information that students provide, to not only identify the most effective teachers working but likely also to set the stage for high added values wherever possible. As Dr. Ferguson states, “‘Kids know effective teaching when they experience it. [...] As a nation, we’ve wasted what students know about their own classroom experiences instead of using that knowledge to inform school[-]reform efforts.’”

Educational initiatives like this one are particularly to interesting to us at Veritas, because we ourselves are continuously paying attention to the dynamics and the results of our tutor-student interactions via similar surveys of experience. Like Dr. Ferguson, we explore these features of the teacher-student relationship in order to consistently identify and improve great teaching. Yet, unlike Dr. Ferguson, we corroborate the surveying practice with additional, less subjective measures of pedagogical effectiveness.

While attending to students’ knowledge via surveys is important and may cleanly generally promote successes in teaching and education, it seems necessary that advocates of the developing policy also consider the limitations of the surveying methodology and the reciprocal nature of the class-based educative process. Teachers may undeservedly become discredited on the basis of the collected opinions of at most 60 children, who may poorly appreciate their actually valiant efforts, while other teachers may equally undeservedly become credited on parallel bases. Surveying people of any age may be easily confounded by the conscious intentions of the people surveyed, themselves subconsciously influenced by social factors like peer-pressure and observational bias (e. g., the teacher’s presence during survey-completion) as easily as circumstantial factors like incidental context (e. g., the middle of an unusually chaotic day). Moreover, especially in such a large survey, how could one separate out the intentional effects of the teacher from the cooperative effects of his/her students? How would the surveyors know that the value added, attributed to the teacher, would not be more accurately attributed to the diligence and cooperative attention of the students themselves; in other words, how could we know whether a teacher ranked highly for maintenance of classroom order, one of the correlate features of a teacher adding value, might be – not a successful order-maintainer himself/herself – rather a middling maintainer happening to be graced by students whose order is easy to maintain, and vice-versa?

Granted the economically precedent limitations of the survey-study in question, the efforts of these educational scientists are majorly valuable. Yet, the ideal accuracies would, no doubt, derive from getting into the classrooms and actually witnessing the dynamics taking place there on a teacher-by-teacher, class-by-class basis. Aspiring toward these ideal ourselves, we at Veritas constantly appreciate and move toward ways in which to best assess and promote the quality of our tutors. We recognize the difficulties inherent in any attempt to do so, and work to refine our processes drawing on multiple methods (including direct observation, surveys, tutor-coaching, and staff-training sessions).  We are committed to delivering the best tailored approaches to education, tailored approaches that mass-surveys and classrooms unfortunately are insufficiently equipped at this time to make or to measure.
