Which pair of variables can't be represented on a scatter plot and why?

a. the heights and ages of kc chiefs players.

b. the names and runs batted in (rbi) statistics of the ny yankees players.

c. the free throws made (ftm) and the free throws attempted (fta) of the sa spurs players.

Option b

Step-by-step explanation:

A scatter plot is one which represents all observations in a graph.

Normally the observations would be for two variables, x and y .  Invariably by convention, x is independent and y is dependent.

Obviously graphing is possible only when x and y both are numerical.  Categorical or other type of variables cannot be plotted in a scatter plot.

Here option a has the heights and ages of KC chiefs players.  Both are numerical and is possible to represent on a scatter plot.

Option b has The names and runs batted in (RBI) statistics of the NY Yankees players. Here name is not numerical and hence cannot be represented on a scatter plot.

Option c has he free throws made (FTM) and the free throws attempted (FTA) of the SA Spurs players. both being numerical  CAN be represented on a scatter plot

Hence answer is option b.

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.
