Answer:
The best measure of center for the second period is mean because there are no outliers that affect the center. (Option A)
Step-by-step explanation:
Outliers are data that are extremely small or large compared to the rest of the data.
As we can see in the data for the second period, the data is within the range of 0 - 4. There are no extremely small or large values from the given data set.
In addition, there are 3 measures of central tendency and these are the mean, median, and mode. Hence, our answer is either A or B.
Since there are no outliers, then the answer is mean. (Option A)
Note that interquartile range and standard deviation are measures of dispersion or how spread the data are. They are not part of the measures of central tendency.
