please help me with this:)

I believe it is C or D.  (C) The IQR is the best measurement of spread for games and movies.

(D) The standard deviation is the best measurement of spread for games and movies.

The explanation why it could be D:

Measures of spread are stats that describes how separated are the group of data between each other.

The measures are range, quartiles, variance and standard deviation. Among these measures, the standard deviation is the one that best expresses the variation, dispersion or spread of a set of values, because is based on the difference between each data and the mean, it takes in count each separation.

The explanation why it could be C:

Our both box plots are highly skewed, therefore, the IQR is the best measurement of spread for games and movies and option C is the correct choice.

I believe it is C, my friend. So I would go with C.

I hope this helps.
