The document contains sample questions about statistical concepts such as mean, median, mode, frequency, and formulas to calculate these measures of central tendency. It also includes examples of calculating the mean, median, and mode for various data sets, as well as the effect of outliers on changing the values of each measure. The questions cover key topics like defining statistical terminology, identifying appropriate formulas, and computing mean, median, and mode from raw data and grouped data.
