What is the median of the data: 1, 2, 3, 3, 5, 6, 8
kobusy [5.1K]

Median: The middle number in the data set when the

data set is written from least to greatest.

Since our data set is already written from least to greatest,

we can just look for the number that appears in the middle.

In this case, it would be 3.

Mode: The number that appears

most frequently in a data set.

Notice that the number 3 appears twice in the data set and no other

number appears more than once. So the mode is 3.

Range: The difference between the greatest number in

the data set and the least number in the data set.

Since the greatest number is 8 and the least number is 1,

the range of the data set will be 8 - 1 or 7.
