Find the mean, median, and mode of the data set. Round to the nearest tenth.

15, 13, 9, 9, 7, 1, 11, 10, 13, 1, 13 (1 point)
• mean = 9.3, median = 8, mode = 13
• mean = 8.5, median = 10, mode = 13
• mean = 9.3, median = 10, mode = 13
• mean = 8.5, median = 10, mode = 8

3. First step: sort the values from low to high.

mean: add them up and divide by how many values there are

median: the middle value -- same number less as greater. If there are an even number of values, take the average of the two center values.

mode: The value(s) which occurs most often

4. mean is another word for average so add them all up and divide by the number of values you had to begin with: 102/11=9.27 and you can round that to 9.3

1, 1, 7, 9, 9, 10, 11, 13, 13, 13, 15

so 10 is the middle number/ median

mode: there are three 13s and two or less of everything else so 13 is the mode

ANSWER C IS CORRECT OMG WOW THAT'S AWESOME GURL!!!!!

18. C - mean = 9.3 median = 10 mode = 13
A - 38
D - mean = 13,156; median = 12,700; no mode; the median is the best choice because it is not skewed by the high outlier.
A - The graph at the top.
A - 30th percentile = 11 90th percentile = 19
