From the Data Bank, choose one of the following variables: age, weight, cholesterol level, systolic pressure, IQ, or sodium level. Select at least 30 values, and find the mean, median, mode, and midrange. State which measurement of central tendency best describes the average and why.
ANSWER:Solution
Step 1 of 5
We have to find the mean, median, mode and midrange for 30 values for any of the variable from the given data set
Find mean mean, median, mode and midrange for the variable age
Mean is the sum of all the values divided by the no.of values
Then Mean
=1166/30
=38.87
Hence Mean=38.87
