ren the following dataset, what is the first quartile? Round to the nearest tenth if necessary.

Question

, 82, 67, 34, 54, 62, 17, 47, 56, 18, 20 (1 point)

Answer 1

To find the first quartile, we first need to put the numbers in order from least to greatest:

17, 18, 20, 34, 47, 54, 56, 62, 67, 82

Now we need to find the median of the lower half of the data set.

The lower half is: 17, 18, 20, 34, 47

Since there are an odd number of data points in the lower half, the median is the middle number, which is 20.

Therefore, the first quartile is 20.
