Question

type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar(s)
the table gives the mean and standard deviation of four data distributions

	mean	standard deviation
distribution 2	21	0.8
distribution 3	19	1.2
distribution 4	20	3.2

distribution has the greatest spread

Explanation:

Step1: Understand spread measure

Spread in a data - distribution is measured by standard deviation. Larger standard deviation means larger spread.

Step2: Compare standard deviations

We have standard deviations 0.2, 0.8, 1.2, 3.2 for Distribution 1, 2, 3, 4 respectively.

Step3: Identify the largest

Among 0.2, 0.8, 1.2, 3.2, the largest value is 3.2 which corresponds to Distribution 4.

Answer:

4
