Question

Exercise 2. Find the mode for each example below.
(a) The following data represent the number of O-ring failures on the shuttle Columbia for its 17 flights prior to its fatal flight:
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 2, 3
(b) The data of the test scores from above:
82, 77, 90, 71, 62, 68, 74, 84, 94, 88
(c) Hair color of ten people in line:
Brown, Blonde, Red, Brown, Brown,
Blonde, Brown, Blonde, Blonde, Red

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.

Expert Solution

Step 1

Concept and definition:

The mode is the value with the highest frequency, that is, the mode is the value in the data-set which occurs the maximum number of the times.

(a)

In this case, the mode value will be 0, because 0 occurs the maximum number of the times in the given data set.

Mode : 0
