The mean is the average
The range is the difference of the lowest and highest ages.
The median is the middle age.
I can't see all of your list, but if you had a list of 1, 5, 7, 9, 15 the median would be 7.
I can't help you on Mode.

look up the definitions of mean, median, mode, range!
mean is simply the average: add up the data points and divide by how many there are
Range is the difference between the largest value and the smallest value. That means subtract the smallest value from the largest value.
median is the middle value (when the values are in sorted order!). if there are an even number of data points, take the average of the two middle values.
mode is the value that occurs most frequently

Mean= #'s added together and divided by the # of #'s that you have
Mode= the # that occurs the most in a set of data
Median= list the #'s from least to greatest, and cross them off equaly on each side till there is a middle #
Range= subtract the largest # from the smallest #
I hope that theise help ypu and your daughter!! :)

Mean-The evening out of data, add all the numbers together and divide by how many numbers you added.
Range-The maximum and the minimum and their difference.
Median-The exact center of a set of data, doen by taking off the first number and the last number, then the second and second last, then the third and third last, etc.
Mode-The number that occurs the most in a set of data, there can be multiple modes, but the mode must appear at lest twice.
I would be able to tell you what they are for your specific set of data, but you did not give the entire set...

Mean is the average, range is the lowest # to the biggest, median is the middle number, mode is the number that appears most often.

mean = average, so add the numbers together and then divide by 9.
range = biggest number minus the smallest number
median = arrange the numbers from smallest to largest. the middle number is the median
mode = most frequently occuring number in the set.

mean: add them up and divide by the number of ages.
range: lowest age - highest age
median: the age that is in the middle when you put them in order.
mode: the most common age.
