Shortly before spring classes begin in January, students will take a comprehensive exam on the theoretical foundations of statistics. There will be a two hour exam on the material of 201A and a two hour exam on the material of 201B. All students taking the exam will receive copies of previous examinations.

You saved the day! I have statistical data!

The adds a curve to the plot representing a moving average over the data. It is not a trend line! also adds some type of margin of error around this smoothing line (I admit that I have not looked deeply into the internals of ggplot2). If we interpret the margin of error loosely as a confidence interval, we can make a statistical conclusion of this graph. Recall that a basic one-sample confidence interval with population standard deviation known is

3. Calculate the test statistic.

Descriptive statistics also help the researcher speak to the limits of who the results can be generalized to. For example, knowing that 100% of the participants were male would imply that they can not necessarily generalize to females.

ABSTRACT. This thesis presents certain recent methodologies and some new results for the statistical analysis of probability distributions on non-Euclidean manifolds. The notions of Frechet mean and variation as measures of center and spread are introduced and their properties are discussed. The sample estimates from a random sample are shown to be consistent under fairly broad conditions. Depending on the choice of distance on the manifold, intrinsic and extrinsic statistical analyses are carried out. In both cases, sufficient conditions are derived for the uniqueness of the population means and for the asymptotic normality of the sample estimates. Analytic expressions for the parameters in the asymptotic distributions are derived. The manifolds of particular interest in this thesis are the shape spaces of k-ads. The statistical analysis tools developed on general manifolds are applied to the spaces of direct similarity shapes, planar shapes, reflection similarity shapes, affine shapes and projective shapes. Two-sample nonparametric tests are constructed to compare the mean shapes and variation in shapes for two random samples. The samples in consideration can be either independent of each other or be the outcome of a matched pair experiment. The testing procedures are based on the asymptotic distribution of the test statistics, or on nonparametric bootstrap methods suitably constructed. Real life examples are included to illustrate the theory.Xiang Zhu Wins ASA Award

The Master of Science in Applied Statistics requires 30 credits: 21 credits in core courses and 9 credits of elective courses. Students must successfully complete at least 24 of these credits at the 600-level or higher, and no more than six credits at the 500-level will be counted towards the degree. A master's thesis or a master's project is optional.

Statistical analysis is a mathematical method of interrogating data.

Using this , I was able to extract information about each thesis submitted for publishing on this website: advisor name, work title, year completed, and level (M.S. or Ph.D.). Student name was removed for anonymity, although anyone can easily perform this analysis manually. The scraping part was easy enough but was only half the battle. I also had to somehow extract the length of each manuscript. To do this, I visited the directory for each manuscript (organized by paper ID number), downloaded it to a temporary directory, and used the Python library to extract the number of pages in the document. I must note that the number of pages returned by pyPdf is the number of raw pages in the PDF document, not the number of pages of writing excluding references, appendices, figures etc. I also manually corrected inconsistencies, such as name formatting, use of nicknames, and mispellings. For example, “Thomas Ferguson” was standardized to “Thomas S. Ferguson.” In the event that two advisor names were given, only the full time Statistics professor’s name was retained. If both were names were full time Statistics faculty members, only the first one was chosen. Sorry about that.

Department of Statistics Theses - University of Washington

This is a Plan A program with final oral examination (defense of the dissertation). A Ph.D. student will select an area of specialization within Biostatistics and will choose a major dissertation adviser from GPS faculty working in Biostatistics, usually in the second or third year of study. The student's program of study will be developed by the student jointly with the Graduate Adviser.
