1. Brenda Scott Academy collected canned food to donate to a local charity. Each homeroom kept track of how many cans it collected. The number of
cans in each homeroom were 78, 81, 71, 66, 63, 87, 80, 40, 56, and 108.
Make a box-and-whisker plot of the provided data.
a) What is the interquartile range of the data?
b) The main office staff collected 56 cans the counseling staff collected 90
cans, and the janitorial staff collected 68 cans. Make a new box-and-
whisker plot to include this data. Please label clearly the median, the
first and third quartiles, the minimum and maximum values, the IQR,
and any outliers should they exist. Also scale the data.

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.
