Question 8 A research hypothesis can state all of the following except,  Question 9 When searching for research on a topic, it is recommended that you use increase the number of search results.  Question 10 What does the following mean in words: H0 µ1 = µ2?  Question 11 A is an idea that is not very well defined.  Question 12 The null hypothesis is represented in symbols as .  Question 13 When hypotheses for a study are said to be mutually exclusive, this means the hypotheses .  Question 14 A research question is and a research topic is .  Question 15 The research hypothesis is represented in symbols as .  Question 16 2 out of 2 points When a researcher classifies data into an order or rank of magnitude, the researcher is using a(n) scale. Question 17 2 out of 2 points In the Are You Equipped? section at the beginning of the chapter, a study was described looking at the relationship between temperature and preference for different movie genres. There were two studies conducted. In the first study, students were given either cold tea or hot tea to drink. In the second study; students were placed in a cold (59–62 degrees Fahrenheit) or warm room (72–76 degrees Fahrenheit). How many levels of the independent variable were there in the first study? Question 18 2 out of 2 points When a researcher classifies data on a scale that assumes equal distance between numbers, the researcher is using a(n) scale. Question 19  2 out of 2 points Dave is conducting research on consumer preference for different products. Dave has participants provide a rank order of the products they prefer. By asking for a ranking of their preferences, Dave is using a(n) scale. Question 20  2 out of 2 points James is conducting a study on professors’ attitudes toward text messaging in class.

Specifically, the article stated there was a positive relationship between childhood aggression and violent cartoons. However, no mention was made of how the term “violent cartoons” was defined. Thus, the researchers had failed to use a(n) when reporting their study. Question 23 An independent variable is the variable in a study that is . 2 out of 2 points Question 24 2 out of 2 points The number of conditions for a specific independent variable is called the . Question 25 Which of the following is a type of measure for a dependent variable?  Question 26  2 out of 2 points Jerry is conducting a study on the type of leadership style (i.e., democratic or autocratic) a person has and the influence that style has on employee satisfaction. What is the independent variable in this study? Question 27  2 out of 2 points The sum of the number of times a person/group responds to a question represents which type of way to assess a measure? Question 28  0 out of 2 points The variable in a study that researchers measure because it is believed to change is called the .
