Abstract:
Previous research efforts have developed and validated various scales potentially useful in evaluating service learning outcomes. The developmental efforts reported for the four scales examined in this study did not include the test-retest reliabilities that would provide assurance to service learning researchers of the long-term stability and therefore usefulness of these measures. Summary estimates of 13-wk. test-retest reliabilities for the scales Civic Participation, Self-efficacy Toward Service, Attitude Toward Helping Others, and College Education's Role in Addressing Social Issues provide service learning researchers with evidence of stability of the scales over the typical duration of service learning courses.

Ratio Level of Measurement
A set of data measured using the ratio scale takes care of the ratio problem and provides complete information. Ratio scale data are like interval scale data, except they have a zero point and ratios can be calculated. For...

Ordinal Level of Measurement
Data measured using an ordinal scale are similar to nominal scale data, but there is one major difference. The ordinal scale data can be ordered. An example of ordinal scale data is a list of the top five national parks in the...
