Question

Find the (a) mean, (b) median, (c) mode, and (d) midrange for the data

Listed below are selling prices (dollars) of TVs that are 60 inches or larger and rated as a "best buy" by a popular magazine. Are the resulting statistics representative of the population of all TVs that are 60 inches and larger? If you decide to buy one of these TVs, what statistic is most relevant, other than the measures of central tendency?

a. Find the mean.

The mean is

(Type an integer or a decimal rounded to one decimal place as needed.)

b. Find the median.

c. The mode(s) is(are)

(Type an integer or a decimal. Do not round. Use a comma to separate answers as needed.)

d. Find the midrange.

The midrange is

(Type an integer or a decimal rounded to one decimal place as needed.)

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.
