Question

without doing any calculation, which of the following dot - plots has the largest standard deviation? a b c dotplot b dotplot c dotplot a

Explanation:

Standard deviation measures the spread of data. In dot - plots, the more spread out the data points are from the mean, the larger the standard deviation. Dot - plot B has data points that are more spread out compared to A and C as the points are in two clusters far from each other, while A and C have more clustered and less spread - out data.

Answer:

Dotplot B
