Explanation / Answer

Mean=sum of observations/total observations

mode is most repeating item

median is miidle most item when data arranged in ascending order

Used R software:

playingtimes <- c(446,244,226,242,242,298,280,224,246,215,266,241,215,258,257,260)
mean(playingtimes)
median(playingtimes)
sort(playingtimes)
mode(playingtimes)

> mean(playingtimes)
[1] 260
> median(playingtimes)
[1] 245
> sort(playingtimes)
[1] 215 215 224 226 241 242 242 244 246 257 258
[12] 260 266 280 298 446
