Find the following in the attachment

mean = To find it, add together all of your values and divide by the number of addends

mode = number that appears most often is the mode.

median = The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest.

range = difference between the largest and smallest values

you need to show the graph

step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
