In a class of 20 students, the height (in centimeters) of some students are recorded as follows: 120,125,130,135,140,145,150,155,160,165,170,175,180,185,190,195,200,205,210,215. What is the average height of the students?

• 167.5

• 52.6

• 68

• 129.2

How do you calculate the mean from a provided set of data?

• Subtract the largest number in the set from the smaller number to find the mean.

• It is calculated by choosing a random number from the set and declare it as the mean.

• To find the mean you take the median of the data set and declare it as the mean.

• It is calculated by adding up all the numbers in the set and then dividing by the total number of values.

What is median?

• Is the smallest number in the dataset.

• Is the number that occurs most frequently in the dataset.

• Is the middle value in a dataset when the numbers are arranged in order.

• Is the largest est number in the dataset

What is mean?

• Is the result of adding all the numbers in the dataset together.

• Is the highest value in the dataset.

• Is the middle value of the dataset.

• Is the sum of all the numbers in a dataset divided by the total numbers in the dataset
