A researcher is examining whether the placement situation for maltreated children affects those children's involvement in juvenile delinquency later on. The researcher collected a sample of juveniles with histories of maltreatment and divided them into three groups: those who stayed with one or both biological parents; those placed in foster care; and those placed in group homes or other facilities. The outcome measure is the number of status and/or delinquent offenses each youth has committed. The data are displayed in the table. Using an alpha of .05, conduct a 5-step ANOVA hypothesis test to find out if there are differences between groups. If appropriate, calculate and interpret omega-squared.
All 5 steps must be shown
| Parent(s) | Foster Care | Residential Facility |
| 5 | 9 | 10 |
| 0 | 7 | 8 |
| 1 | 1 | 6 |
| 4 | 4 | 9 |
| 8 | 3 | 11 |
| 9 | 0 | n3 = 5 |
| n1 = 6 | 2 | |
| n2 = 7 |

Solution
We will use One Way Anova to to find out if there are differences between groups and the procedure is as follows
(5) Conclusion
It is concluded that the null hypothesis Ho is not rejected. Therefore, there is not enough evidence to claim that there are differences between groups, at the α=0.05 significance level.

A researcher is interested in examining whether there are
differences in students’ sense of safety across schools. She
selects three schools and surveys five students from each school.
The tab labeled Question 3 reflects the answers from this
survey—the higher the score, the safer the student feels. Is there
a difference between these schools in the students’ sense of
safety?

A researcher is interested in examining whether different
practice strategies have an influence on the accuracy of basketball
players' free throws. The researcher collected data from a sample
of 18 participants who were classified in one of three groups: (1)
6 players who received no special practice, (2) 6 players who spent
30 minutes just imagining that they were shooting baskets, and (3)
6 players who spent 30 minutes actually practicing shooting
baskets. After participating in the experiment for two...

Questions 9-13 are based on Scenario 3. A
researcher is interested in examining whether exposure to “green
spaces” (such as those found in nature) can influence stress levels
(as measured by cortisol). Researchers place participants in a room
lined with green plants for one hour and measure their stress
levels before and after being in the room.

A researcher is
interested in determining whether the illumination level in a room
affects how quickly clients can be put into a trance. The time (in
seconds) it took for five clients to go into a trance when it was
done in a room that was lit with low light was measured, as was the
time it took for the same clients to go into a trance in a brightly
lit room. The theory being tested does not predict which...

A researcher is interested in studying whether a new stretching
technique affects the time needed to complete a certain running
exercise. The times of 4 randomly selected participants were
measured before the new stretching technique was used, and then the
times for the same participants were measures after the new
technique was used. The resulting data is

A researcher is evaluating whether a new intervention affects
the average reported anxiety symptoms in a sample of 49 college
students. A survey from the previous semester found that the
population reported a mean anxiety score of 22 with a standard
deviation of 7. The sample completes the same measure of anxiety,
with an average score of 20. The researcher sets their alpha level
at .05 and performs a two-tailed test to determine whether anxiety
increases or decreases after the...

In a study examining whether taking a statistics course
influences students’ reasoning skill, a researcher first gave a
reasoning task to 5 students who have never taken a statistics
course, and then the students took a brief statistics lecture which
lasted 3 hours. After the lecture, the same five students took the
reasoning task again. Their performance scores are summarized in
the table below.

*A researcher would like to find out whether a particular diet
affects a person’s cholesterol reading. She records the cholesterol
readings of 23 men who ate cow meat for dinner every night, 24 men
who ate chicken and 19 men who ate pig; her data appears in the
table to the right. She wants to know whether the differences in
the average readings are significant; i.e., whether the average
reading of all men who eat cow is different from the...
