Question

The New York Times reported that Apple has unveiled a new iPad marketed specifically to school districts for use by students (The New York Times website). The -inch iPads will have faster processors and a cheaper price point in an effort to take market share away from Google Chromebooks in public school districts. Suppose that the following data represent the percentages of students currently using Apple iPads for a sample of U.S. public school districts.

Click on the datafile logo to reference the data.

a. Compute the mean and median percentage of students currently using Apple iPads.

Mean		(to decimals)
Median		(to the nearest whole number)

b. Compute the first and third quartiles for these data.

First quartile		(to decimals)
Third quartile		(to decimals)

c. Compute the range and interquartile range for these data.

Range		(to the nearest whole number)
Interquartile range		(to decimals)

d. Compute the variance and standard deviation for these data.

Variance		(to decimals)
Standard deviation		(to decimals)

e. Are there any outliers in these data? Enter the number of outliers. If an amount is zero, enter "0".

value(s) would be considered outlier(s).

f. Based on your calculated values, what can we say about the percentage of students using iPads in public school districts?

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
