Question

Based on the data set shown, which of the following is a true statement?

Answer 1

Start by identifying your mean.

Add all of your values together and then divide by the total number of values.
11/11 is 1

So your mean is 1.

The mode is the most common number in the data set, which is also 1. The number 1 is most frequent in the set.

So this makes A the correct answer.

Answer 2

The mean, median, and mode are equal to 1. So among the choices, the first one is correct - mean = mode

Mean - an average of the given set of number; to find this, add the numbers and divide it by 11 (the number of given data)
   = (-1 + -1 + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3) / 11
   = 1

Median - the middle or center of the given set; to find this, arrange the numbers in numerical order, then get the center or middle number as the median
   = -1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
   = [-1, -1, 0, 1, 1,] 1, [1, 2, 2, 2, 3]

Mode - is the value that occurs most of the time in the given set; so obviously number 1 occurred four times so 1 is our mode
