Question
Find the mean, median, and mode of the data set. (Enter DNE for any values that do not exist.)
Data set: 9, 2, 8, 2, 5, 4
Solution
To find the mean, median, and mode of the data set, follow these steps:
Step 1: Arrange the data in ascending order: 2, 2, 4, 5, 8, 9
Step 2: Calculate the mean (average). Add up all the numbers and then divide by the number of numbers. (2+2+4+5+8+9) / 6 = 30 / 6 = 5
Step 3: Find the median (the middle number). Since there are 6 numbers, the median is the average of the 3rd and 4th numbers. (4+5) / 2 = 4.5
Step 4: Determine the mode (the number that appears most often). In this case, the number 2 appears twice, more than any other number, so the mode is 2.
So, the mean is 5, the median is 4.5, and the mode is 2.
