Free Samples
These are the two two general types of sampling
What are probability and non-probability?
Statistical analyses are broken into two categories, one category describes the other category tests hypotheses.
What are descriptive and inferential statistics?
Often, this type of research is identified by a large (50+) number of participants
What is quantitative?
This method collects opinions, beliefs, or attitudes about certain phenomena
What are surveys?
These descriptive stats include mean, median, and mode.
What are measures of central tendency?
This popular non-probability sampling method involves selecting participants that are readily available
What is convenience sampling?
Hypothesis testing focuses on two hypotheses, one where something happens (at a significance level) the other where nothing happens
What are the alternative and null hypotheses?
If you're "exploring", 9 times out of 10 you're using this approach
What is qualitative?
Participants gathered in a room to discuss their experiences with a phenomenon
What is a focus group (interview)?
The dispersion from the mean is measured by this stat.
This probability sampling method involves are members of a population having an equal chance of being selected.
What is simple random?
Significance is typically set at one of two levels
What are p<.05 or p<.01?
Researchers set out to use a Postpositivist approach
What is quantitative?
Participants are randomly assigned into two groups . One group receives a treatment, the other nothing in this type of research design
What is an one-way (two group) experiment?
The IVs in this type of analysis can be continuous or categorical, but the DV must be continuous.
This sampling method break participants into categories.
What is stratified sampling?
What is ratio (continuous)?
Researchers have designed a project that revolves around addressing inequity in college admissions using this qualitative leaning worldview
What is Transformative?
Researchers email a survey to potential participants on their experiences of homelessness. The researchers are exposing their survey to this type of bias.
What is sampling bias?
Researchers exploring the difference in NCE scores for students at Caldwell and Montclair State use this analysis.
What is an independent samples t-test?
Pass this frigid type of sampling along to anyone who's eligible.
What is snowball sampling?
In an ANOVA, the Dependent variable must be this level of measurement
What is categorical?
If a researcher is looking to understand the interaction between age and study habits, they are using this approach
What is quantitative? Although you could alter this to be qualitative
A 2X2 design is used to analyze study habits and sleep time on test scores. After conducting their experiment, researchers find that sleep and studying yields higher test scores, an example of this
What is an interaction?
Researchers administer an assessment called "the benefits of pizza eating" to measure levels of depression in teens, displaying this validity issue
What is a threat to face validity?
