the kellen school district gives awards to its schools based on overall student attendance. the data for attendance are shown in the table, where low represents the fewest days attended and high represents the most days attended for a single student.

school low high range mean median iqr σ
high school w 108 180 72 169 150 47.5 29.5
high school x 112 180 68 160 124 49.5 32.4
high school z 130 180 50 162 151 39.5 27.5

part a: if the school district wants to award the school that has the most consistent attendance among its students, which high school should it choose and why? justify your answer mathematically. (5 points)

part b: if the school district wants to award the school with the highest average attendance, which school should it choose and why? justify your answer mathematically. (5 points)

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
