Add the totals for each section and find the average. Then add the average scores for each section and find the overall average.

__7 and half Total
___7__ Average
I get a total of 7.5.
Divide it by 14 to find the average.
What would be the average
What is
7.5 / 14 = ________
0.53
That does not make any sense for the assigment
Rounding it is 0.54
It makes sense since all of the scores were either 0, 0.5 or 1..
To find the total score for each section, you need to add up the scores for each individual criterion. In this case, we are given the scores for each criterion in the Ease of Use section:
- Skills needed to operate the program are in range of the child: 0.5
- Children can use the program independently after the first use: 0.5
- Accessing key menus is straightforward: 0.5
- Reading ability is not prerequisite to using the program: 0
- Graphics make sense to the intended user: 1
- Printing routines are simple: 1
- It is easy to get in or out of any activity at any point: 1
- Getting to the first menu is quick and easy: 0.5
- Controls are responsive to the touch: 0.5
- Written materials are helpful: 0
- Instructions can be reviewed on the screen, if necessary: 0
- Children know if they make a mistake: 0
- Icons are large and easy to select with a moving cursor: 1
- Installation procedure is straightforward and easy to do: 1
To find the total score for the Ease of Use section, simply add up all of these individual scores:
0.5 + 0.5 + 0.5 + 0 + 1 + 1 + 1 + 0.5 + 0.5 + 0 + 0 + 0 + 1 + 1 = 7.5
Next, to find the average score for the Ease of Use section, divide the total score by the number of criteria (14 in this case):
7.5 / 14 = 0.53 (rounded to two decimal places)
You can repeat this process for the other sections to find the total scores and average scores for each section. Once you have the average scores for each section, you can add them up and divide by the number of sections to find the overall average.
