# PSAT Math : How to find mode

## Example Questions

### Example Question #1 : How To Find Mode

Looking at the table, what is the difference of the mean minus the mode.

1.0

0.5

–0.5

–1.0

–0.5

Explanation:

The mode is 3 and subtracting 3 from 2.5 gives -0.5.

### Example Question #1 : How To Find Mode

Find the mode of the following set of numbers:

1, 6, 3, 6, 5, 9

6

8

5

9

6

Explanation:

Mode is the most frequently occuring number in a set. 6 appears most frequently since there are 2 sixes but the rest of the numbers only appear once. The mode is 6

### Example Question #3052 : Sat Mathematics

Find the mode.

Explanation:

The mode is the number that appears the most often. 9 appears three times.

### Example Question #4 : How To Find Mode

What is the mode of the following set of numbers?

24, 38, 26, 27, 7, 27, 34, 12, 13

Explanation:

The mode is the number that appears the most in a given set of numbers.

### Example Question #1 : How To Find Mode

Consider the following dataset:

The arithmetic mean of the dataset is .

The median of the dataset is .

The range of the dataset is .

The mode of the dataset is .

Which of the following statements is true?

Explanation:

In general:

In this case the mean is:

To obtain the median, arrange the observations from smallest to largest:

When there is an odd number of observations, the median is the middle value. In this case:

The range is the difference between the largest and smallest value:

The mode is the value that occurs most often in the dataset:

Since:

we can conclude:

### Example Question #2 : How To Find Mode

 Marker Colors Students Blue 13 Pink 10 Orange 5 Brown 5 Green 7

The above chart shows the number of students in a class who chose each of the five marker colors available.

What is the mode of the above chart?

Explanation:

The mode of a problem is the most common number, i.e. the number that appears the most times in a given set of data. In this case, only one number is repeated. Therefore, the mode is 5.

### Example Question #3 : How To Find Mode
