a) Drop-down options: na, one-way ANOVA, within subjects ANOVA, or two-way ANOVA
b) Drop-down options: Yes or No
c) Drop-down options: na, Trivial Effect, Small Effect, Medium Effect, Large Effect
e & f) Drop-down options: Yes or No
(a). Approriate test for hypothesis is one-way anova because we want to compare the average past, present and future satisfaction scores of individuals and we have only one factor which is of temporal (i.e., past, present and future). So, our hypothesis are:
(b) for computation of anova in spss follow the given steps:
OUTPUT:
(c). Formula of effect size is: SSbetween / SStotal = 36.400/83.600 = 0.435. Therefore magnitude of effect size is large.
(d). Since our significance (p-value) for anova test is less than 0.05. So, we may reject our null hypothesis at 0.05 level of significance and conclude that "Atleast one of the temporal means is different on life satisfaction"
(e).By using SPSS output:
a) Drop-down options: na, one-way ANOVA, within subjects ANOVA, or two-way ANOVA b) Drop-down options: Yes...
Application Exercise: A social psychologist is interested in how optimism is related to life satisfaction. A sample of individuals categorized as optimistic were asked about past, present, and projected future satisfaction with their lives. Higher scores on the life satisfaction measure indicate more satisfaction. Below are the data. What can the psychologist conclude with an a of 0.01? past present future 22 24 27 26 28 27 28 29 30 30 26 27 26 28 29 a) What is the...

An educational psychologist has developed a mediation technique to reduce anxiety. The psychologist selected a sample of high anxiety students that are asked to do the mediation at two therapy sessions a week apart. The participants' anxiety is measured the week before the first session and at each subsequent session. Below are the anxiety scores for the participants. What can the psychologist conclude with α= 0.05? before session 1 session 2 9 6 8 5 8 6 9 6 8...
A university instructor uses different teaching methods on three separate computer science classes. The instructor wants to evaluate the effectiveness of the methods by comparing the grades between the classes. The grades have been transformed and are in the table below.

A team of comparative psychologists are interested in the maternal behavior or rats. In an experiment, 10, 20, and 30 day-old rat pups were separated from their mothers. They then recorded the time (in seconds) required for the mother rats to retrieve the pups. The psychologists were interest in whether retrieval time varies with age. The data are given below. What can be concluded with an α of 0.05? 10 days old 20 days old 30 days old 16 11...

Researchers gave a family planning survey was given to the head(s) of household in a local community. In particular, one question asked the head(s) of households to indicate if they think the community has a great, some, or no need of family planning counseling. In addition, they were asked to indicate how many children are in the household. Researchers want to know if the number of children in the household is impacted by family planning counseling. What can they conclude...
