find the mean, median, and mode of the following data: (round to 1 decimal place as needed) 35, 17, 20, 31, 17, 27, 33, 17, 27, 18 mean = 24.2 median = enter an integer or decimal number more... mode = 17
Answer
Explanation:
Step1: Arrange data in ascending order
17, 17, 17, 17, 18, 20, 27, 27, 31, 33, 35
Step2: Find the median position
There are (n = 10) data - points. The median position for (n) even is (\frac{n}{2}) and (\frac{n}{2}+1). Here, (\frac{n}{2}=\frac{10}{2}=5) and (\frac{n}{2}+1 = 6).
Step3: Calculate the median
The median is the average of the 5th and 6th ordered - data values. (\text{Median}=\frac{18 + 20}{2}=\frac{38}{2}=19)
