Question

question 1 which of the following quantitative data sets would you expect to have the larger standard deviation? o the collection of heights, measured in inches, of 1st - through 6th - grade students in an elementary school. o the collection of heights, measured in inches, of all 12 - th - grade students in a high school. o the length in inches of newborns at a hospital in one year.

Explanation:

Step1: Understand standard - deviation concept

Standard deviation measures the spread of data. More variation leads to a larger standard - deviation.

Step2: Analyze each data set

Newborn lengths have relatively little variation as newborns are of similar sizes. Heights of 1st - through 6th - grade students have some variation but students in these grades are still growing in a somewhat predictable range. Heights of 12th - grade students have more variation because by 12th grade, students have completed a significant portion of their growth and there is a wider range of physical development, including differences due to gender, genetics, etc.

Answer:

The collection of heights, measured in inches, of all 12th - grade students in a high school.
