We are given with the number of jumps per student. To get the mean, we simply have to add all of them and divide by the number of students
mean number of jumps = 203 + 245 + 237 + 233 + 90 + 100 + 100 + 277 + 265 + 264 + 265 + 285 + 288 + 291 + 291 + 290 + 300 + 224 + 200 + 257 + 290 + 279 + 266 + 288) / 24
To get th median, arrange the data from lowest to highest and determine the middle value.
The mean (rounded to the nearest hundredth) is 242.83. The median is 265. Hope this helps I hate finding this stuff.
