Q.

0.3,0.45,0.35,0.15,0.2

Find the median:

Identify Order: Identify the ascending order of the given data set. $\newline$ We need to arrange the data points from least to greatest to find the median. $\newline$ Data set in ascending order: $0.15$ , $0.2$ , $0.3$ , $0.35$ , $0.45$
Find Median: Find the median of the numbers. $\newline$ Since there are $5$ data points, the median will be the middle number after arranging the data in ascending order. $\newline$ The middle number is the third number, which is $0.3$ .
Verify Median: Verify the median. $\newline$ To ensure there is no math error, we can count the numbers again to confirm that $0.3$ is indeed the middle number. $\newline$ There are two numbers before $0.3$ ( $0.15$ and $0.2$ ) and two numbers after $0.3$ ( $0.35$ and $0.45$ ), confirming that $0.3$ is the median.
