A researcher is interested in whether technology has changed people’s preferences in leisurely activities based on their age range. She chooses the concept of using eBooks as a replacement for physical books. She gathers a group of 10 individuals in each of the following age groups: 10-year-olds, 30-year-olds, 50-year-olds, and 70-year-olds. For each group she has them rate on a scale of 1-10 how much they prefer an eBook compared to a physical book. The data for this study is presented below: 10-year-olds 30-year-olds 50-year-olds 70-year-olds 8 7 5 4 7 6 4 6 9 5 6 3 10 7 9 4 5 5 10 6 6 4 4 5 7 9 3 4 9 10 5 7 8 4 4 2 9 8 7 3 For this assignment you will: State populations and hypotheses Conduct a One-way ANOVA in SPSS Report the results using proper APA format If there was a significant result, conduct post-hoc tests Describe the results to this study What are the implications of this study What are the strengths and weaknesses of this ANOVA *Be sure to include your SPSS output.

Answer:
The SPSS output is:
The hypothesis being tested is:
H0: µ1 = µ2 = µ3 = µ4
Ha: At least one means is not equal
The p-value is 0.003.
Since the p-value (0.003) is less than the significance level (0.05), we can reject the null hypothesis.
Therefore, we can conclude that at least one means is not equal.
There is a significant difference between 10-year-olds and 50-year-olds.
There is a significant difference between 10-year-olds and 70-year-olds.
There is a significant difference between 30-year-olds and 70-year-olds.

Q.4 A researcher is interested in whether people’s level of
loneliness would vary as a function of their relationship status
(single vs. in a relationship), and how such difference might
depend on whether people own a pet or not. She recruited a group of
participants, asking them about their relationship status, pet
ownership, and the perceived level of loneliness. The data are as
below, with a higher number denoting greater level of
loneliness:
Single/ no pet

A researcher is interested in whether or not there is a
difference in student’s performance based on the study methods they
use. Participants are assigned one of three different study methods
(read the text and re-read it, read and answer prepared questions,
and read then create your own questions). There are 6 people in
each group and the researcher measures the participants’
performance on a test. Perform a hypothesis test and show all four
steps. Hints: Use a two tailed...

A researcher is interested in whether children’s memory of a
witnessed event can be changed through false information.
Participants (10-12 years old) watch a recorded video of a car
accident and then take part in a discussion regarding what they
remember. Participants are randomly assigned to one of three
conditions: experimenter-delivered false information,
confederate-delivered false information, or control. In the
experimenter-delivered condition, the experimenter introduces the
incorrect information during the discussion. In the
confederate-delivered condition, the incorrect information is
introduced...

1. A
university researcher is
interested in whether
recent recruitment efforts
have changed the
type of students
admitted to the
university. To test
this, she randomly
selects 50 freshmen
from the university
and records their
high school GPA.
The mean is 2.90
with a standard
deviation of 0.70.
The researcher also
knows that the mean
high school GPA of
all freshmen enrolled
at the university
five years ago was
2.75 with a
standard deviation of
0.36. The researcher

A researcher is interested in the effects of “mindfulness
training” on people’s sense of well being. She divides
15 people into three groups: one group is a waiting control group;
one group does mindfulness training for a 45 day protocol; and the
third group does the training for 90-days. Following the
training she measures number of reports of “feeling well without
significant anger, depression or anxiety for a full day” for
2-weeks. The results are below.
Number
of reports of well being...

A researcher was curious about whether people’s attitudes are
related to their behaviors. As a simple experiment, the researcher
measured people’s attitudes and behaviors regarding housework.
On the attitude side, the researcher measured the level of
agreement on the statement “It is much better for everyone
involved in housework: strongly agree, agree, disagree, and
strongly disagree” On the behavioral side, the respondents are
asked to estimate how many hours of housework they do per week.
Based on your analysis of...

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.
Question 9
What is the null hypothesis for scenario 3?
Group of answer choices
H0: µposttest = µpretest

In a cognitive psychology experiment, the researcher is
interested in whether encoding condition has a significant effect
on memory for a list of words. She recruits 32 subjects to
participate in the experiment. Each recruited subject is randomly
assigned to either encoding condition A or encoding condition B.
The researcher would like to leave the hypothesis non-directional
without predicting which encoding condition would lead to better
memory, and she sets the significance level at α = .05 for a
two-tailed...
