Median, Mode, And Range help!
@hkm91 can you please tell why the answer is option c? I'm lost
mean is the avg of all 11.3
range is from 7.3 to 11.3 which is 4
range is from 7.3 to 11.3?
i thought range was from 11 to 14?
so range is 4 (10 to 14), mode is 10, only option C has thoset so i can safely assume that you're right :) thanks
First add 5 hours to each of the times first so you get the new times. thus you'll see the most popular time is 10hours, this is the mode. then add up all the new hours and divide this by the number of participants which is 79/7=11.3hrs this is the mean (or average). next you'll notice that the highest new time is 14 hours and the new lowest is 10 so the range is 14-10 =4. the median is achieved by listing the new times in order starting with the lowest to the highest and then picking the middle number which is 11 (this is call ranking the numbers) so there you go.
