You have administered a test to your classmates to measure how likeable they think you are on a scale of 1 to 10. A score of 1 is represents the least likeable whereas a score of 10 represents the most likeable. See the results of this test below.

 

Participant 1 = 9

Participant 2 = 8

Participant 3 = 8

Participant 4 = 10

Participant 5 = 2

Participant 6 = 8

Participant 7 = 9

Participant 8 = 3

Participant 9 = 1

Participant 10 = 5

 

1. Conduct an analysis of central tendency and dispersion for this data set.

 

 

2. Report the type of test used and what it was used to test by filling in the blanks of the following sentence.

 

 

“______________________ were computed to summarize the data for the ________  data set. ____________________ were computed to understand the variability  of scores for the _________ data set.”

 

 

3. Fill in the blanks of the following sentence.

 

 

“The following are the results of this analysis; N = ______, M=_____, SD=_____.” 

 

 

4. Write a sentence that states what your results mean in terms of your experiment – in words that an inexperienced scientific reader could understand.
