|
|
construct validity |
it it measuring what its supposed to |
|

criterion-related validity |
using outside sources/ tests to to validate |
|
|
face validity |

predictive validity |
do the measures we are using predict what we are studying. Scoreson the measure predict behavior on a criterion measured at a time in the future |
|
|
concurrent validity |
scores on the measure are related to a criterion measured at the same time. current validity |
|
|
convergent validity |
scores on the measure are related to other measures of the same construct |
