Correlation
This type of correlation is used when both variables are continuous and the relationship is linear.
What is Pearson correlation?
This scale of measurement involves categories without any order or hierarchy.
What is the nominal scale?
In a bivariate regression, this variable is the one being predicted.
What is the dependent variable, or "Y"?
This type of validity examines how well a test measures the construct it claims to measure.
What is construct validity?
What is norm-referenced-assessment?
This type of correlation is used to measure the strength and direction between ordinal variables.
What is Spearman's rank correlation?
This scale of measurement includes equal intervals between values and has a true zero point.
What is the ratio scale?
This is the name of the prediction equation that best represents the data in a bivariate regression analysis.
What is the line of best fit?
This term refers to the consistency of a test over time.
What is reliability?
In a criterion-referenced test, this is the key focus of the evaluating the scores.
What is whether an individual meets a specific performance standard or criterion?
In a study examining how an older adult ranks in flexibility and age in elderly individuals, this correlation coefficient should be calculated.
What is a Spearman's rank correlation coefficient?
This scale of measurement allows for meaningful differences between values, but lacks and absolute zero.
What is the interval scale?
If a fitness test consistently produces similar results each time it's administered to the same individual, it is said to have this type of reliability.
What is test-retest reliability?
A fitness instructor completes a brief, weekly evaluation of basic strength skills to monitor their client's progress. This is an example of what type of assessment?
What is formative assessment?
A researcher wants to examine the relationship between the number of hours spent training each week and sprint performance (in seconds) for a group of track athletes. The Pearson correlation coefficient is calculated to be -0.72. What does this imply about the relationship between training hours and sprint performance?
What is a moderate, negative relationship?
A researcher develops a questionnaire to assess athletes' stress, reported as "low", "moderate", and "high". This is the scale of measurement represented in the survey.
What is ordinal scale of measure?
In a bivariate regression model, a coefficient of determination (r2) of 0.85 would indicate this percentage of the variation in the dependent variable is explained by the independent variable.
What is 85%?
This type of validity assesses how well a test's results align with a well-established measure of the same construct.
What is criterion validity?
This type of assessment allows for the comparison of an individual's scores to others who have completed the test, usually by age and gender.
What is a norm-referenced assessment?
In an experiment on the effect of diet on athletic test scores, a researcher finds that r = 0.54 between caloric intake and endurance scores among marathon runners. This is the interpretation of the relationship.
What is a moderate, positive relationship.
In a study looking at athletes' perceived exertion during training, participants are asked to rate their intensity on a scale from 1 to 10, where 1 is "very light" and 10 is "maximal effort". This is an example of which type of measure?
What is interval scale of measure?
A researcher wants to predict an athlete's body fat percentage based on weekly strength training volume using a bivariate model. The equation is:
Body Fat % = 25-0.15(strength training volume)
This is the interpretation of the slope.
What is negative slope of -0.15?
For each unit of strength training volume, body fat percentage is predicted to decrease by 0.15%.
A fitness researcher designs a checklist test to assess cardiovascular fitness and compares the test results to those obtained using an established treadmill test. The new test produces results that are highly correlated with the treadmill test. This is the type of validity that is being assessed.
What is criterion validity?
A coach wants to assess the strength of athletes in their team using a 1-rep max test. They use the results of this test to compare athletes' performance to a criterion level (e.g., strength standards). What type of assessment is the coach using?
What is criterion referenced assessment?
