Use the Descriptive Statistics analysis tool when possible. Remember, for the qualitative variables, this includes constructing and commenting upon a frequency table and a discussion of the mode. For the quantitative variables, explain why the mean or the median is the best representation of central tendency and the standard deviation or IQR of dispersion. This is decided by examining the histogram and boxplot. Identify the appropriate measures and state the associated values from the descriptive statistics table. 2. 3.
