Example Question #151 : Statistics And Probability
Mrs. Hooper's Algebra 1 test just completed their 10th test of the year. They were currently studying mean, so Mrs. Hooper gave them the list of scores in the class and asked them to find the mean. What should their answer be if the scores were as listed below?
The mean means the average of all of the scores. You have to add up all of the scores and divide by the total. If you add up all scores you would get . You need to divide the total by , and the answer is .
If you round to the nearest, you would get as the mean score.
Example Question #152 : Statistics And Probability
Find the mean of the following data set:
4, 2, 7, 8, 8, 2, 8, 10, 7
If necessary, round your answer to the nearest whole number.
To find the mean of a data set, we add all the values together and divide by the number of values. In other words
Example Question #153 : Statistics And Probability
Find the mean of the following:
The mean is the average of the dataset. Simply add all the numbers and divide by the total amount of numbers in the dataset.
Add the numbers.
Divide this number by three to get the mean.
The mean is 1.
Example Question #153 : Statistics And Probability
Find the mean of the following set of numbers:
1,1,3,7,7,8,9,12,15
To find the mean, simply add all of them numbers and divide by their quantity. Since there are 9 numbers, I will be dividing by 9. Thus,

Example Question #159 : Statistics And Probability
Find the median of the following dataset:
Arrange the dataset from least to greatest.
Since there are four numbers, the median is the average of the center two numbers.
Average the two numbers.
The answer is:
Example Question #160 : Statistics And Probability
