Refer to the Journal of Experimental Social Psychology (Vol. 45, 2009) study of whether buying gifts truly buys love. Recall that study participants were randomly assigned to play the role of gift giver or gift receiver. Gift receivers were asked to provide the level of appreciation (measured on a 7-point scale where 1 = "not at all" and 7 = "to a great extent") they had for the last birthday gift they received from a loved one. Gift givers were asked to recall the last birthday gift they gave to a loved one and to provide the level of appreciation the loved one had for the gift. The researchers wanted to know if the average level of appreciation is higher for birthday gift givers than for birthday gift receivers. a. Why is this study designed? b. Specify the key elements of the study: experimental unit, response variable, factor, and treatments.

(a) A designed study (experiment) deliberately imposes some treatment on individuals in order to observe their responses. An observational study tries to gather information without disturbing the scene they are observing.
The participants were randomly assigned to play the role of gift giver or gift receiver. This then implies that the treatments gift giver” and "gift received” were imposed on the individuals, thus the study is a designed studty.
(b) The experimental units are the individuals on whom an experiment is performed.
Experimental units=Study participants
A response variable (or dependent variable) is a variable that measures an outcome or result of a study.
Response variable=Level of appreciation of gift
The factors are variables whose levels are manipulated hy the experimenter and thus these variables are controlled by the experimenter.
Factors: Giver or receiver The treatments are what the subjects are subjected to.
Treatments: Giver and Reciever.

A researcher is conducting a study to examine the effects of cognitive behavior therapy for the treatment of social anxiety in a sample of 16 participants. He measures the social anxiety scores of participants before the tratment and then again after treatment and the resulting data is as follows:
\(n=16, M_0=5, s =4\)
a) What type of design is this study (single-sample, independent measures, repeated measures)
b)State the null and alternate hypotheses
c) Using an \(\displaystyle\alpha\ level\ of\ {.05}{\left(\alpha={.05}\right)}\), identify the critical values of t for a 2-tailed test.

In a similar study using the same design (sample of \(n = 9\) participants), the individuals who wore the shirt produced an average estimate of \(M = 6.4\) with \(SS = 162\).
The average number who said they noticed was (population mean) 3.1. Calculate a One Sample t-test using a two-tailed test with \(\displaystyle\alpha={.05}\).

The American Journal of Political Science (Apr. 2014) published a study on a woman's impact in mixed-gender deliberating groups. The researchers randomly assigned subjects to one of several 5-member decision-making groups. The groups' gender composition varied as follows: 0 females, 1 female, 2 females, 3 females, 4 females, or 5 females. Each group was the n randomly assigned to utilize one of two types of decision rules: unanimous or majority rule. Ten groups were created for each of the \(6\ \times\ 2=12\) combinations of gender composition and decision rule. One variable of interest, measured for each group, was the number of words spoken by women on a certain topic per 1,000 total words spoken during the deliberations. a. Why is this experiment considered a designed study? b. Identify the experimental unit and dependent variable in this study. c. Identify the factors and treatments for this study.

Is the gift you purchased for that special someone really appreciated? This was the question investigated in the Journal of Experimental Social Psychology (Vol. 45, 2009). Toe researchers examined the link between engagement ring price (dollars) and level of appreciation of the recipient \(\displaystyle{\left(\text{measured on a 7-point scale where}\ {1}=\ \text{"not at all" and}\ {7}=\ \text{to a great extent"}\right)}.\) Participants for the study were those who used a popular Web site for engaged couples. The Web site's directory was searched for those with "average" American names (e.g., "John Smith," "Sara Jones"). These individuals were then invited to participate in an online survey in exchange for a $10 gift certificate. Of the respondents, those who paid really high or really low prices for the ring were excluded, leaving a sample size of 33 respondents. a) Identify the experimental units for this study. b) What are the variables of interest? Are they quantitative or qualitative in nature? c) Describe the population of interest. d) Do you believe the sample of 33 respondents is representative of the population? Explain. e. In a second, designed study, the researchers investigated whether the link between gift price and level of appreciation was stronger for birthday gift givers than for birthday gift receivers. Toe participants were randomly assigned to play the role of gift-giver or gift-receiver. Assume that the sample consists of 50 individuals. Use a random number generator to randomly assign 25 individuals to play the gift-receiver role and 25 to play the gift-giver role.
