We are asked to find the mode and median for the distribution

2,5,4,7,3,4,6,5,4

(1) To find the median we put in ascending (or descending) order:

2,3,4,4,4,5,5,6,7

The median is the value with the same number of data points below it as above it. If the distribution has an odd number of data points (as this one does) then the median will be one of the data points.

Here 4 has 4 data values below it, and 4 data values above it.

The median is 4.

(2) The mode is the data value(s) that occur the most often (and at least twice.)

Since there are 3 4's, the mode is 4.

Sorry I was thinking of mean

Mode is the most number of the same numbers found which in this case would be 4

2, 5, 4, 7, 3, 4, 6, 5, 4

Mode is to add up all the numbers and divide by the number there

2, 5, 4, 7, 3, 4, 6, 5, 4/9 = 4

The median is the middle

2,3,4,4,4,5,5,6,7

The median is 4
