Question

What conclusion can be determined from the dot plot below?

A dot plot showing two dots above 6, 7, 8, 9 and 10 each.

The number of observations is 5.
The median of the data set is 5.
The mean of the data set is 8.
The range of the data set is 8.

Answer 1

Well, the number of dots is the number of observations
The median is the middle point of the data, crossing off the smallest and biggest data values, then the second smallest, second biggest, etc., until you get to the middle
mean is adding up all the values and then dividing it by the total amount of data points
range is the biggest number minus the smallest number
