A group of 8 students was asked, "How many hours did you watch television last weet Here we the responses
4.15, 19, 11, 6, 16.9.15
Find the mean and median number of hours for these students,
If necessary, round your answers to the nearest tenth
?
Means (hours
Methan: I hours

The mean is the average, add the numbers together and divide by the number of students asked:

Mean = 4 + 15 + 19+ 11 + 6 + 16 + 9 + 15 = 95/8 = 11.875 rounded to the nearest tenth = 11.9

Median is the middle value, list the numbers from smallest to largest:

4, 6, 9, 11, 15, 15, 16, 19

There ia an even number, so find the middle two numbers, add them together and divide by 2:

Median = 11 + 15 = 26 / 2 = 13

Mean: 11.9

Median:13

Step-by-step explanation:

The mean of the amount of hours watched is also known as the average. To find the average of a group of values, you need to add all of them together and then divide by the number of values. In this case:

To find the median, the first step is to arrange the values from least to greatest: 4,6,9,11,15,15,16,19

Now, if there is an odd amount of values, you can simply take the middlemost one. However, since there is an even amount, you need to average the two middlemost values, while in this case is (15+11)/2, or 13. Hope this helps!
