| Question | Answer |
| Alternate forms reliability | participants in a research or testing scenario is given two different versions of the same test at different times. then scores are compared to see if it is a reliable form of testing. -Test-retest reliability |
| Interrater reliability | raters agree in their observation cohen's kappa |
| Internal consistency reliability | assessing reliability using responses at only one point in time split half/cronbach's alph/item total correlations |
| Split-half reliability | Correlation between one half of measure and the other •Spearman-Brown split-half reliability coefficient |
| Test-retest reliability | measures the same individuals at two points in time. reliable coefficient/greater than or equal to .80/may be artificially inflated/alternate form reliability |
| Concurrent validity | research that examines the relationship between the measure and a criterion behavior at the same time (concurrently). |
| Content validity | comparing the content of the measure with the universe of content that defines the construct |
| Convergent validity | (scores should relate) scores on the measure in question are related to scores on other measures of the same construct or similar constructs |
| Discriminant validity | (shouldn't be related to it no way) measured is not related to variables it should not be related |
| Face validity | (this appears to be right, can't trust it though) –The measure appears to accurately assess the intended variable –Not always a good indicator of validity |
| Predictive validity | (weather forecast) –Research that uses a measure to predict some future behavior –The criterion measure is based on future behavior or outcomes |
| Reactivity | •When awareness of being measured changes how the respondent behaves •May be minimized by allowing for respondent time to become comfortable with assessment •Nonreactive or unobtrusive measures |
| Nominal scale | no numeric scales (male/female) |
| Ordinal scale | Rank ordering Numeric values limited (4 stars for restaurant) |
| Interval scale | interval between values Numeric properties are literal (intelligence/temperature/ACT) |
| Ratio scale | (ratio between 18-40 year olds) Zero indicates absence of variable measured (reaction time/weight/age) |
