Research Basics
Practice is designed to enhance this, while research tests hypotheses
What is well being
This type of sampling occurs when participants recruit their friends to join a study
What is snowball sampling?
If r = 0.60, this percentage of variance is explained
What is 36%?
This ethical principle involves treating people as autonomous agents
What is respect for persons?
This scale type would be used to record gender in statistical software
What is nominal?
This statistical method would determine the most important variables predicting diabetes
What is multiple linear regression?
This section of a manuscript should be able to stand alone
What is the abstract?
This type of validity is compromised by using dietary questionnaires
What is internal validity?
This type of hypothesis states there is no statistical relationship between variables
What is a null hypothesis?
The population that a researcher actually has access to in their study
What is the accessible population?
This test is used to check normality in a dataset in a pearson correlation.
What is the Shapiro-Wilk test?
This ethical principle involves maximizing benefits and minimizing risks
What is beneficence?
Blood pressure values would be recorded on this type of scale
What is interval?
A p-value of 0.03 in a normality test indicates this about your data
What is that it violates the assumption of normality?
The introduction should contain what?
Information gap, thesis statement, small background
Statistical inference is compromised when this is too small
What is sample size?
The CONSORT statement is meant to maintain adequate reporting for this type of study
What are randomized controlled trials?
This type of validity is limited when a study only uses college students
What is external validity?
The Durbin-Watson test checks for this assumption in regression
What is independence of observations?
This principle asks who should receive benefits and bear burdens of research
What is justice?
This type of research methodology would best suit understanding firefighters' perceptions
What is qualitative research?
Removed
Statistical methods should appear in this section of a manuscript
What is the methods section?
This concept in Hill's causality refers to biological plausibility
What is coherence?
When viewing these bars, 95% of data points will be within 2 of the mean
What are standard deviation bars?
In a study examining exercise effects and BP, this demographic factor could be a moderating variable.
a. gender
b. exercise
c. BP
gender
When variables show high correlation with each other in regression, this problem occurs
What is multicollinearity?
These two mechanisms explain how placebos work
What are expectancy and classical conditioning?
When comparing a questionnaire to accelerometer data, this validity is being tested
What is concurrent validity?
In correlation, this value indicates a relationship
What is an r-value?
T/F. The methods section should not interpret how results answered research objectives
True
A linear rise in cancer rates with cigarettes smoked shows this causality concept
What is biological gradient?
T/F . Statistical significance doesn't always equal biological importance
True
This type of bias occurs when recruitment is solely from a college campus
What is selection bias?
This represents the difference between observed and predicted values in statistical analysis
What is a residual?
Using placebos is most ethical in this situation
What is when no known treatment exists for a condition?
To establish this type of reliability, multiple raters test the same person and compare scores
What is inter-rater reliability?
This effect size would be considered large in statistical analysis
What is d > 0.8?
This core component ties together introduction, methods, and results
What is the discussion?
The directionality problem is refering to what?
if you can nog determine what the IV and DV are because you dont know what happened first.
