Testing, Testing...
This is the key difference between a t-test and an ANOVA.
What are the number of groups of independent variables?
This type of test requires that data meet the following assumptions: variable must be normally distributed, interval or ratio scale of measurement, selection of participants is independent, and variance of the comparison groups is equal.
What is a parametric test?
The conclusion reached when a researcher rejects the null hypothesis.
What is that there is no real differences between groups?
This type of research involves collecting data to test hypotheses or to answer questions about people's opinions on some problem or issue.
What is survey research?
Because researchers doing this type of research interact much more often and intimately than other researchers, there are added ethical concerns.
What are qualitative researchers?
This test of statistical significance determines if two groups' means differ more than would be expected by chance.
What is a t-test?
This is the first decision to be made in the selection of an appropriate test of significance.
What is determining if a parametric or non-parametric test is required?
This category of statistical analysis is primarily concerned with making generalizations about the population from significant findings about the sample.
What is inferential statistics?
This type of research involves collecting data to determine whether and to what degree a relationship exists between two or more quantifiable variables.
What is correlational research?
This is the point in a study at which a participant can withdraw.
What is any time?
This analysis is used when comparing the means of multiple groups of IVs with one continuous dependent variable.
What is ANOVA?
A non-parametric test should be used for this type of data.
What is nominal?
What is a Type 1 Error?
This statistic indicates the size and direction of the relationship between two variables.
What is a correlation coefficient?
The ethical principle concerned with honoring commitments and keeping promises including fulfilling one’s responsibilities of trust in professional relationships
What is Fidelity?
This analysis us utilized to control the effect of extraneous covariates when comparing means.
What is MANCOVA?
This analysis is NOT a parametric statistic/analysis.
What is chi-square?
When a researcher is concerned about committing a Type 1 Error, they should use this significance level to reject or accept the hypothesis.
What is .001?
In this type of research, the researcher attempts to determine the cause or reason for existing differences in the behavior or status of groups or individuals.
What is causal-comparative research?
Researchers must weigh the _____ against the _____ to participants to minimize potential harmful effects on participants.
What are the risks and benefits?
This analysis is used when comparing means between 2 or more continuous independent variables and 1 continuous dependent variable.
What is multiple regression?
These types of analysis are fairly robust.
What are parametric analyses?
The type of error that occurs when a researcher concludes there were no differences between groups when, in fact, there are differences between groups.
What is a Type II Error?
This type of study is used to determine which variables are the most highly related to the criterion variable.
What is a prediction study?
The number of ethical codes in the AERA Code of Ethics.
What is 22?
