Calculate the mean, median, and mode of this data.

Calculate Mean: First, let's calculate the mean. Add up all the hourly pay rates and then divide by the number of data points. $\newline$ $5.00 + 4.21 + 4.97 + 5.00 + 5.00 + 5.29 + 5.05 + 5.50 + 5.79 + 5.00 + 5.40 + 5.20 + 5.10 + 5.06 + 4.50 + 4.50 + 5.50 + 4.50 + 5.00 + 5.00 + 5.50 = 106.57$ $\newline$ There are $21$ data points. $\newline$ Mean = $\frac{106.57}{21}$
Add and Divide: Now, let's do the division to find the mean. $\newline$ Mean = $\frac{106.57}{21} = 5.08$
