A large group of teenagers is divided into two smaller groups of 125 each, and each group watches a different movie. One group watches a love story while the other group watches a movie containing several scenes with violence. The teenagers are then asked questions to uncover unconscious associations and determine their level of aggression. I. What is the population? II. What is the sample? III. Is the study observational or experimental? Justify your answer. IV. What are the variables? V. For each of those variables, what level of measurement (nominal, ordinal, interval, or ratio) was used to obtain data from these variables?

2. sirm3d

the population is the the group of respondents, in this case, 250 teenagers. the sample is 125 in either movie category.

3. DarkendSinz30

Okay

4. sirm3d

when you ask, that is observational. when you measure, that is experimental.

5. DarkendSinz30

sorry

6. DarkendSinz30

What would be considered the sample?

7. sirm3d

125 teenagers in each movie category.

8. DarkendSinz30

okay was confused there for a minute

9. sirm3d

a study is observational when you gather "answers" from respondents. this answers are generally subjective. in an experimental study, the responses are actually measured, like the number of mg of a drug administered to a lab. animal.

10. sirm3d

the variables being measured in the study are unconscious association and level of aggression.

11. DarkendSinz30

So would you say the variables would be ratio or interval due to the questions asked?

12. sirm3d

yes

13. DarkendSinz30

yes to which there was 4 choices?

14. sirm3d

my take is on interval.

15. DarkendSinz30

okay I knew it had to have been one of the last 2 choices simply because of the numbers and the people asked I was going to take interval because it was asking the teens the questions

16. sirm3d

i take back my answer. it would be ratio, since there is an absolute zero level of aggression.

17. sirm3d

furtermore, a level 6 of aggression is considered to be 3 times as much as a level 2 aggression.

18. DarkendSinz30

oh okay didn't know that

19. DarkendSinz30

I have 3 more questions to do

20. sirm3d

the difference between between interval and ratio is in the concept of absolute zero. 0 degree temperature does not mean no temperature, so temperature is interval.

21. DarkendSinz30

Oh okay now I understand it a little better
