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?

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

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.

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

my take is on interval.

DarkendSinz30Best ResponseYou've already chosen the best response.0
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

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

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

I have 3 more questions to do
 one year ago

sirm3dBest ResponseYou've already chosen the best response.1
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.
