SimpleRandom: Simple Random Sample

In tigerstats: R Functions for Elementary Statistics

Description

An app to investigate the visual and numerical differences between a sample and a population. A sample is drawn from the input population and then a variable of choice is selected by the user. If a categorical variable is chosen, the user sees a bar chart with red bars designating the population and blue bars designating the sample. Simultaneously, a summary table (of percents) is output to the console for both the population and the sample. If a numerical variable is chose, the kernel density plot for the population is plotted in red and the histogram for each new sample is plotted in blue. Simultaneously, the summary information for minimum, maximum, quartiles, median, mean, and standard deviation are output to the console for both the population and the sample. The size of the sample can be changed to explore how this affects statistics and the plots.
