Validity and reliability Test with spss

Validity and reliability Test with spssThese post of Validity and reliability test will explain clearly, starting from the definition, criteria, to decision making test. The explanation will be presented separately between the validity and reliability test. We will provide examples in real way testing using SPSS program. Follow this explanation:

Validity test

Validity testing is used to determine the degree of validity and validity of the measuring instruments used in the study (eg questionnaire). That is, a valid research instrument is a truly appropriate instrument for measuring what will be measured.

The criteria that can be used for validity testing are:

Instrument valid if correlation value> 0.3

Instrument valid if correlation value> r table (r table value can use formula DF = n-2)

Level of significance used:

1. 0.05 / 0.1

2. 0.025 / 0.05

3. 0.01 / 0.02

4. 0.005 / 0.01

Criteria that can be used for reliability testing:

Reliable instrument when the value of cronbach alpha> 0.6

A reliable instrument if the value of cronbach alpha> r table
