Question

21 find the mode of the following data set: 121, 232, 172, 275, 115, 174, 425, 232, 185 (options: 245, 185, 232, 210)

Explanation:

Step1: Recall the definition of mode

The mode of a data set is the value that appears most frequently.

Step2: Count the frequency of each data point

Let's list out the data points (assuming the data set is: 121, 220, 172, 275, 115, 174, 425, 220, 185).

• 121: appears 1 time
• 220: appears 2 times
• 172: appears 1 time
• 275: appears 1 time
• 115: appears 1 time
• 174: appears 1 time
• 425: appears 1 time
• 185: appears 1 time

Step3: Identify the mode

Since 220 appears more frequently (2 times) than any other value, the mode is 220.

Answer:

220
