Answer:
Median = 23
Mean = 163/7 = 23.3 (1 d.p.)
Step-by-step explanation:
Given data set:
19, 18, 23, 24, 31, 32, 16
Median
The middle value when all data values are placed in order of size.
Given data values in size order, from smallest to largest:
[tex]\sf 16, 18, 19, \boxed{\sf 23}, 24, 31, 32[/tex]
The middle value is 23, so the median of this data set is 23.
Mean
The sum of all data values divided by the total number of data values.
[tex]\begin{aligned}\implies \sf mean & =\sf \dfrac{19+18+23+24+31+32+16}{7}\\& = \sf \dfrac{163}{7}\\ & = \sf 23.28571429...\\ & = \sf 23.3\:(1\:d.p.)\end{aligned}[/tex]
