:'''PC3.''' Once you've found the variable, compute and present a series of statistics on it that you should already be familiar with. Use functions to compute the mean, median, variance, standard deviation, and interquartile range? | :'''PC3.'''

:'''PC4.''' Although these basic functions all exist, many things you will want to do in the future won't have functions. Write R code to compute these three statistics by hand: mean, median, and mode. It's OK if getting the answer involves some eyeballing or counting this by hand. But do get the answer and be ready to walk us through how you did it. | :'''PC4.''' Although these basic functions all exist, many things you will want to do in the future won't have functions.
