Construct a stem-and-leaf plot of the data. (use the tens digit as the stem and the ones digit as the leaf. enter your answers from smallest to largest, separated by spaces. enter none for stems with no leaves.) 5 6 7 8 9 part (b) are there any potential outliers? if so, which scores are they? why do you consider them outliers? the only outlier is 50 because it lies 1.5 × iqr below the first quartile. the only outlier is 98 because it is the largest value in the data set. the two outliers are 50 (because it lies 1.5 × iqr below the first quartile) and 98 (because it lies 1.5 × iqr above the upper quartile). there are no outliers in the data set because there are no large gaps in the stem-and-leaf plot.

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.
