Assignment task: Descriptive statistics are used to summarize data. Learn about the different kinds of descriptive statistics, the ways in which they differ from inferential statistics, how they are calculated and more.
Q1. Imagine that you are interested in measuring how many people in a population are obese or overweight. A common way that obesity is tracked in the population is with body mass index (BMI). Your boss provides you with a data set of 12 study participants' BMIs and asks you to calculate the basic descriptive statistics. The BMI are 28, 40, 23, 34, 35, 18, 24, 35, 21, 22, 38 and 19. Your boss asks you for a summary of your findings.
Q2. Calculate the mode, mean, standard deviation, variance, range, and outliers; and report whether these data are normally distributed. Review the video for information about descriptive statistics.
