Question

What is the mode of the data set?
78, 82, 91, 78, 92, 77, 80, 74, 81

Answer 1

Answer:

The mode is 78

Step-by-step explanation:

Mode: The digit that has been repeated the most in a specific data.

To determine the mode of the data, let's arrange the data in ascending order.

Arranging the data in ascending form, we get:

• ⇒ 74, 77, 78, 78, 80, 81, 82, 91, 92

In the ascending data, we can see that: (Refer to underlined and bolded text)

• 74 has been repeated once

• 77 has been repeated once

• 78 has been repeated twice

• 80 has been repeated once

• 81, has been repeated once

• 82 has been repeated once

• 91 has been repeated once

• 92 has been repeated once

Since 78 has been repeated the most, 78 is the mode of the data.
