Sort Data: Sort the data in ascending order to make it easier to create the frequency distribution.
Choose Intervals: Choose appropriate class intervals for the frequency distribution. Since the data ranges from 22 to 168, we can use intervals of 10, starting from 20 up to 170.
Count Data Points: Count the number of data points falling into each class interval to create the frequency table.
Calculate Relative Frequency: Calculate the relative frequency for each class interval by dividing the frequency by the total number of data points, which is 150.
Calculate Cumulative Frequency: Calculate the cumulative relative frequency by adding the relative frequency of the current class interval to the cumulative relative frequency of the previous interval.
Draw Histogram: Draw the histogram using the class intervals on the horizontal axis and the frequencies on the vertical axis.
Draw Frequency Polygon: Draw the frequency polygon by plotting points at the midpoints of the class intervals at the corresponding frequency and connecting them with straight lines.
