Question

Lite Snacks Crisp Company’s quality control department regularly samples packets of crisps to gauge the average contents. During one production run the results were:

Number of Crisps	18	19	20	21	22	23	24
Number of boxes	11	15	61	47	34	22	10

a.) Find the mean, median and mode.

b.)Display the information graphically. (boxplot)

c.) The company would like to advertise the average number of crisps in a packet. Which figure should be quoted and why? (Assuming there are no legal restrictions on which value is given.)

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
