ARM final exam 2023 completely solved!!
Which of the following are assumptions of survey research
*Respondents are willing to give the required information to researchers
*Respondents have the information the researcher requires
. A group of students take an Advanced Research Methods test just before the
end of semester and one when they return to school at the beginning of the next
semester. The scores on both tests are examined for a correlation. This is an
example of measuring
Test-retest reliability
If you want to ensure that different age groups are included in your probability
sample in the proportions in which they occur in the population, you would need
to use:
Stratified sampling
The multiple dichotomy method of coding is used with:
Closed questions where more than one response option may be selected
. Which of the following statements is/are true?
Commonality is the proportion of variance in a variable explained by the extracted
factors
Which of the following is an example of a parametric test?
*analysis of variance
* one-sample t-test
* Pearson correlation
The interpretation of a 2 × 2 chi-square test for independence is like what other
type of statistical test?
d. two-independent sample t-test
A researcher reports the following equation for a best-fitting straight line to a set
of data points: . Which value is the y-intercept?
3.24
A researcher has participants complete a survey regarding their level of restraint
when eating. Participants were assigned to groups based on their current health
status (lean, overweight, obese) and gender (male, female). What type of factorial
design is most appropriate for this study?
a between-subjects factorial design
The normality assumption states that the population of X and Y scores form a
bivariate ("two variable") normal distribution, such that
a. the population of X and Y scores are normally
distributed
b. for each X score, the distribution of Y scores is
normally distributed
c. for each Y score, the distribution of X scores is
normally distributed
What is the problem with the following data for computing a correlation?
Factor 1 Factor 2
