Answer: 28.5
Step-by-step explanation:
To find the median, the data should be arranged, first, in order of least to greatest or greatest to the least value.
So firstly we arrange the values : ( from smallest to largest )
- 24, 25, 26, 27, *28*, *29*, 30, 30, 31, 34
After being arranged we find that there are 2 numbers in the middle ( 28 & 29 ) So we add them then we divide them by two because there cannot be two medians: (28+29) / 2=?
= (28+29) / 2 = ?
= 57/2= 28.5
