To find the mean of the numbers, add all the numbers and divide by how many numbers are in the list:

190 + 209 +243 + 288 + 317 = 1247

1247 divided by 5 = 249.4

To find the median, list the numbers from smallest to largest. The median is the number in the middle:

243

The mode is the number that is repeated more than any other. This list of numbers has no mode.
