Question

Using designs with more than two levels of an independent variable allows researchers to a. compare a placebo group to the control and experimental groups. b. compare more than two kinds of treatment in one study. c. accomplish all of the other alternatives. d. compare two or more kinds of treatment with a control group.

A two-way ANOVA means that the experimental design includes a. two independent variables b. all of the above c. two dependent variables d. two types of variance

Answer #1

Ans:

1)Using designs with more than two levels of an independent variable allows researchers to:

**compare two or more kinds of treatment with a control
group. **

(option d is correct)

2)A two-way ANOVA means that the experimental design includes:

**two
independent variables**

(option a is correct)

The two-way ANOVA compares the mean differences between groups that have been split on two independent variables (called factors). The primary purpose of a two-way ANOVA is to understand if there is an interaction between the two independent variables on the dependent variable.

TRUE / FALSE to the questions below
11. In
basic experimental designs, the interaction of two independent
variables can be
studied.
12.
Field experiments are conducted in laboratory settings.
13.
External validity has to do with the determination of whether the
independent variable
was the sole cause of the changes in the dependent variable.
14. A
major advantage of the static group design is that we have some
assurance that the
groups were equal on the variables...

The
t statistic compares two groups on one independent variable that
has two levels. We can use the t statistic to compare a sample that
has a level of an independent variable, or we can use two samples
from the same populations and give them two different levels of an
independent variable. You will design a two group study with one
independent variable for this question. Choose an independent
variable that has two levels. The two levels can be 1.)...

Are there any advantages to having more than one independent
variable in an experimental design? If so what are they? What about
more than one dependent variable?

I want to design a psychology research study in spss asseing
the impact of an independent variable (regular exercise over 8
weeks) on a dependent variable (depression). impact on depression
measured as change in scores on the widely accepted BDI-II
depression diagnostics test. Measuring points at start and end of
the 8 weeks.
For this my understanding is that the repeated measures t-test
is right.
I want to also compare the results of this group receiving
treatment with a control...

A statistical measure of the association between two
variables is called a
independent variable
b.
correlation coefficient
c.
dependent variable
d.
placebo
e.
control variable

Fill in the blank:
a. The df-within for an ANOVA with 6 groups and 10 participants
in each group is _____
b. Error variance is ____ -- groups variance?
c. In a 2x2 ANOVA matrix of means, cell means tell us about the
interaction and _____ means tell us about the main effects.
d. The two primary statistical assumptions about the dependent
variable that should be met when you're conducting an ANOVA are
that the populations are _____ and _____...

For each of the studies, please indicate the
following:
1)Independent variable
True/Quasi?
2)Is there more than one
IV?
3) The levels of the independent
variable
4) Dependent variable
5) the level of measurement (NOIR) of the DV
6) Between (BS) or within-subjects (WS)?
7) What type of design is being used?
8) What is the appropriate statistic? (for correlation list all
variables)

Researchers using the Roland-Morris Disability Questionnaire as
its tool for collecting disability data want to compare two
treatment groups. They believe that a 2.5 group difference would be
important to them. The literature implies that the common standard
deviation for the groups for this questionnaire is 3.7 points.
a. What sample size do they need to detect this difference at
80% power, with a level of significance of .05 using a two-tailed
independent test?
b. How would you adjust these...

Choose a question/problem you are interested in, come up with a
testable hypothesis, and design a simple experiment to help answer
this question. In your design, address the following:
1. What is your hypothesis? People infected
with COVID 19 recover at a faster rate when given an injection of
remdesivir than those that receive no injection or
hydroxychloroquine.
2. Identify the following:
a. Independent variable – what variable are you
manipulating
b. Dependent variables – what are you
measuring; what...

For the following scenario, identify the design (e.g,. two-way
independent), name the factors, name the levels name the dependent
variable, give the # of cells, give the # of possible simple
effects, and total N.
A) A group of researchers looked at the long-term
impact of divorce on first, second, third, and fourth year college
students' levels of optimism and trust. They compared students from
divorced families and students from intact families (n = 12)
