Step 5. Repeat Step 4 to create the remaining intervals. You should keep making intervals until you get to an interval that includes the highest score in the distribution above. Present the intervals in a chart like that given below. Make sure you put the interval with the lowest value (worst test scores) at the bottom of the chart and the interval with the highest values (best test scores) at the top.Step 6. Set up a table with the columns as shown below. Create your own table on a separate piece of paper. (a)Apparent Limitsof the Interval(b)Midpoint of theInterval(c)FrequencyStep 7. Count the frequency (number of scores) in each interval and list them in column (c) of yourtable. (Add up the frequencies and be sure you have n=66 scores in all.) Also note the midpoints of each interval (b).3.Draw a frequency histogramof the above data. Each bar should be centered on the midpoint of the interval (from (b) above). Be sure to label both axes.4.Draw a frequency polygonof the above data, plotting the points at the midpoints of the intervals. Label both axes.Part 2: Enter your three-column table of data (from Part 1, Step 6) into an Excel spreadsheet. Generate and print the below the charts that you’ll create in Excel. As you enter your data from Step 6into Excel, enter your interval of worst test scores at the top of the table and the interval with the highest values at the bottom of the table. This will make your x axes logical. 10 pts.
As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
