What is the mean, median, and mode of 3,8,13,4,9,15,7,8,5,

Mean:  8

Median:  8

Mode:  8

Step-by-step explanation:

Find the average

Mean: 3 + 4 + 5 + 7 + 8 + 8 + 9 + 13 + 15 = 72

Divide by the amount on numbers:  72 / 9 = 8

8 is the average

Find the middle

Median:  3, 4, 5, 7, 8, 8, 9, 13, 15

8 is the middle

Find the most common

Mode:  3, 4, 5, 7, 8, 8, 9, 13, 15

8 is most common

Step-by-step explanation: Here, we want to find the mean, median, and mode for the data set. Let's begin by finding the mean.

The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set. So to find the mean of the data set shown here, let's begin by adding the numbers.

This will be divided by how many numbers are in the set which is 9.

Adding the numbers we get 72.

72 is divided by the number of numbers in the set or 9.

72 divided by 9 is equal to 8.

So the mean of the set of data shown here is 8.

Next, let's find the median.

The median is the middle number in the data set when the data set is written from least to greatest. So let's write our data set from least to greatest.

We have 3, 4, 5, 7, 8, 8, 9, 13, 15.

So the median will be the middle number or 8.

Lastly, let's find the mode.

The mode is the number that appears most frequently in a data set.

Notice that the number 8 appears twice in our data set so we say that the mod of this data set is 8.
