Key Concepts

Descriptive Statistics

Descriptive statistics involve methods for summarizing and describing the main features of a data set. This includes the calculation of averages, percentages, frequencies, and other measures that provide insight into the overall structure and distribution of the data being analyzed in the study.

Categorical Data Analysis

Categorical data analysis focuses on data types where values represent distinct categories rather than numerical measurements. This involves assessing the frequency and proportion of observations in different categories—such as the presence of varsity teams or campus setting—which allows for the comparison of different groups within the dataset.

Arithmetic Mean

The arithmetic mean is a measure of central tendency which is calculated by summing a set of numerical values and dividing by the number of values. In the context of the question, it is used to compute averages such as the average endowment and the average percentage of applicants admitted, providing a single value that summarizes the central point of the data distribution.

Percentage Calculation

Percentage calculation involves converting a ratio or fraction of a count relative to the total number into a figure out of 100. In this data analysis context, it is used to compute what portion of the schools have specific attributes, like possessing NCAA Division III varsity teams or a particular campus setting, by dividing the count of schools with the attribute by the total count of schools and then multiplying by 100.
