Answer:
The correct answer is a) Mean =13173.6; median is 12765 no mode ; The median is the best choice because it is not skewed by the high outlier.
Step-by-step explanation:
Step 1
Arrange the data starting from the smallest to the biggest value. The arranged values are listed here as 11850, 12700,12765,13075,15478.
Step 2
Read the median and determine the mode in this data set.
The median is the value in the center which is 12765. Since every value only appears once, there is no mode for this data set.
Step 3
Calculate the mean of this data set. The mean is calculated by adding up all the values and dividing by the number of distance data available. In this case the data has 5 values, we will divide by 5. This calculation is shown below,
The mean for the data set is 13173.6
Step 4
The best measure of central tendency for this data is the median because it is not skewed by the high outlier. The mean is bigger than 4 of the data points and is skewed by the biggest distance.
