Question

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

Explanation:

Standard deviation measures the spread of data. Data points in dot - plot A are more clustered around the center, indicating less spread. In dot - plot B, the data is more spread out with two separate clusters far from each other. Dot - plot C has a bit more spread compared to A but less than B. So, the data in dot - plot A has the least spread and thus the smallest standard deviation.

Answer:

B. Dotplot A
