You can put this solution on YOUR website! The frequency distribution of the hourly wage rates (in dollars) among blue-collar workers in a certain factory is given in the following table. Find the mean (or average) wage rate, the mode, and the median wage rate of these workers. (If necessary, round your answers to two decimal places.)
mean=
mode=
median=
Wage Rate 10.40 10.50 10.60 10.70 10.80 10.90
Frequency 60 90 75 120 60 45
---------
mean = ?
Sum of wage/freq products = 4786.5
Sum of the frequencies = 450
-----
mean = 4786.5/450 = 10.64
================
mode is the most frequent wage rate = 10.7
================
median is the middle score is the average of the 225th and 226th score =
(10.60+10.70)/2 = 10.65
===========================
