Answer

Explanation:

Step1: Arrange data in ascending order

$3.25,3.25,3.66,3.83,4.44,4.52,4.57,4.69,4.74$

Step2: Calculate the median

Since there are 9 data - points (an odd number), the median is the $\left(\frac{n + 1}{2}\right)$-th value. Here $n=9$, so the median is the 5 - th value. Median $=4.44$

Step3: Calculate the mean

Mean $=\frac{3.25+3.25 + 3.66+3.83+4.44+4.52+4.57+4.69+4.74}{9}=\frac{36.95}{9}\approx4.11$

Answer:

Median = $4.44$ Mean = $4.11$
