What is the median of the following set of data?
0.6, 0.5, 0.9, 0.4, 0.3, 0.7, 0.2

Median: 0.5

Step-by-step explanation:

Arrange the following set of data from least to greatest:

0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.9

then find the middle number (the median).

since there are seven numbers in the data set we divide it, by doing this:

{0.2, 0.3, 0.4} 0.5 {0.6, 0.7 0.9}

Therefore, the median for the data set is 0.5!

(i'm sorry if you don't get it, i'm just bad at explaining)

50-38=12

step-by-step explanation:

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
