In the following video, you will learn how to graph the results of
your MSWO preference assessment.

Now that you have learned how to take data, you will learn how to score and interpret the results!
The whole array was represented one more time and the results are shown on the third row
To calculate the results Add the total value of each item’s selection order and write it in the column of each item
For example, for the car add 6 +4+4 = 14
For the bike add 6 +3+3 =12
For the cube add 2+2+2=6
Do the same for the spinner 1+1+1=3
Now add the ones for the ducks 3+6+6 =15
Alright we have one more item, the action figure add 6+5+5=16
Once you have calculated the total value of each item, write down the item names from lowest to highest total value
In this case, the spinner has the lowest total value, 3
The second item with the lowest total value is the Cube, then the bike, after that the car, then the duck, and the item with the highest total value is the action figure
The item with the lowest total value is the most preferred, In this case, the spinner is most preferred
The item with the highest total value is the least preferred, In this case, the action figure is least preferred
When teaching new skills, use the top three items. As we mentioned in the previous section, the most preferred items are the most likely items to function as potential reinforcers
and reinforcers increase behavior. We want to use these potential reinforcders to increase our clients skills
Now get ready to take a quiz!
