The Law School Admissions Test (LSAT) is given to students seeking admission to law school. If those who score high on the LSAT ultimately have higher grades in law school, while those with lower scores have lower grades, the LSAT is said to have?
face validity
predictive validity
concurrent validity
test-retest reliability
The LSAT is said to have predictive validity if those who score high on the LSAT ultimately have higher grades in law school, while those with lower scores have lower grades. Predictive validity essentially means that a test is able to accurately predict future outcomes or performances related to the domain it is designed for, in this case, the success in law school.
To determine if the LSAT has predictive validity, researchers would collect data on the LSAT scores of students and also track their subsequent academic performance in law school. By analyzing the relationship between LSAT scores and law school grades, researchers can determine if there is a significant correlation or predictive power of the LSAT for success in law school.
It's worth noting that face validity refers to whether a test appears to visually measure what it is designed to measure. Concurrent validity refers to the correlation between a test and a similar established measure conducted at the same time, while test-retest reliability refers to the consistency of scores when the same test is taken multiple times by the same individuals.
