Mean, Median, Mode, and Range

To find the median of a data set. . .

1. Put all the number of the set in order. 2. Find the middle number. 3. If there are two middle numbers, add them together, and divide by two.

Another word for the word mean is. . . .

. . . the average.

Another word for the range is . . . .

. . . the difference in the distance.

The mode is. . . .

. . . the number that occurs most frequently in a data set.

The median is the. . . .

. . . middle number in a set of data

To find the average or mean of a set of terms I follow these steps:

1.Add all the numbers in the data set together. (set total) 2. Write down the total amount of numbers in set. (set amount) 3. Divide the set total by the set amount.

What is the mean, or the average of the following set: 100, 250, 300, 200, 500, 10

1.Add all the numbers in the data set together. (set total) 2. Write down the total amount of numbers in set. (set amount) 3. Divide the set total by the set amount.=226.67 The mean is 226.67
