Time Management Assignment

Using your original data from your time management assignment during Week 1, you will engage in the tasks

listed below. Use the keys provided for you to manage your data, complete the assignment and submit your

work to the instructor or via Canvas Assignment Manager. There are instructions for completing your graphs

below each table, in addition to the more complete, step-by-step instructions in the “creating a graph on line”

supportive document under this week’s Module. Also, use the “examples for creating tables” supportive

document to help guide you in creating your frequency distribution tables.

Task 1

You will complete a frequency distribution tables using your 5 tasks as the x-values.

1) x- values = the 5 tasks that you spend the most time doing

2) f = the frequency of engaging in each task

3) cf = the cumulative frequency of engaging in each task

4) % = percentages for each task (round to at least 2 spaces to the right if your calculations do not result in

whole numbers)

5) c% = the cumulative percentage (round to at least 2 spaces to the right if your calculations do not result

in whole numbers)

Frequency Distribution Table 1:

(NOTE: Your X values here are the 5 tasks)

X f cf % c%

∑f =

Task 1A

Using the data above, create a bar graph. Your 5 tasks should be placed on the x-axis with frequencies on the

y-axis.

(EXTRA: There are many different ways to create a bar graph on your computer. A bar graph can be

created by using graph applications on Word. However, I found a nice web site directed toward kids that

help you to create a bar graph quickly & easily! http://nces.ed.gov/nceskids/index.asp. You can copy and

paste the graphs into your assignment, or you can choose to forward them to me via email. Make sure

that your name is somewhere on the graph so I know who’s graph it belongs to. Have some additional

ideas to help your classmates? Let them know on the Discussion Board!

Task 2

You will complete a grouped frequency distribution table using segments of time as your x-values. Use the

table provided for you below to record your data & complete your calculations. Be sure to review the “rules” for

creating and developing a grouped frequency distribution table!

1) A grouped frequency distribution table of the 24 hour period (remember your rules about constructing a

grouped frequency distribution table) So, your x-values will be “time” or “hours in the day,” such as

12:00 – 1:59, 2:00 – 3:59, etc..

2) f = the frequency of engaging in all 5 of the tasks for each class interval (time segment)

3) cf = the cumulative frequency of engaging in all 5 tasks for each class interval

4) % = percentages for each task (round to 2 spaces to the right if your calculations do not result in whole

numbers)

5) c% = the cumulative percentage (round to 2 spaces to the right if your calculations do not result in whole

numbers)

Grouped Frequency Distribution Table:

(NOTE: Your X values here are segments of time)

X f cf % c%

∑f =

Task 2A

Using the data above, create a frequency polygon with your class intervals (time segments) on the x-axis and

frequencies on the y-axis. Make sure to review the “rules” regarding frequency polygons in your Class Notes!

You may also use the resource indicated above (http://nces.ed.gov/nceskids/index.asp). There are additional

instructions within your “create a graph on-line” document to help you “begin” and “end” your line on the x-

axis.

Go back & check the following:

1) Did you put a % symbol at the end of all of your percentages?

2) If you encountered values that are not whole, did you round to at least 2 places to the right of the

decimal?

3) If you forwarded your graphs to me, did you put your name somewhere on the graph?
