The frequency polygon below illustrates data collected by a company on the daily wages of some employees. Determine the values that complete the frequency table.
The following frequency polygon illustrates data, collected by a company, on the daily wages of some employees. Determine the values that complete the frequency table.
A frequency polygon graphs information from a frequency table by plotting the mid-point of each set and joining the points by a line.
The mid-point for 20 is 25, the mid-point for 30 is 35, the mid-point for 40 is 45, the mid-point for 50 is 55, and the mid-point for 6070 is 65. Look along the vertical axis to find the related frequencies: 4, 5, 14, 12, and 5.
