Suppose you wish to give a survey that measures job motivation by asking five questions. YOU are responsible for mastering SPSS, and YOU need to practice, find alternative information sources, and fill in any gaps in your knowledge/skill sets regarding use of SPSS and statistics. Descriptives for each variable and for the scale, summary statistics across items, inter-item correlations and covariances, reliability estimates, ANOVA table, intraclass correlation coefficients, Hotelling's T 2, and Tukey's test of additivity. Therefore, the correct data will be determining true the results of research quality. For rater reliability where ratings are usually Factor analysis on the questionnaire for construct validity was performed using tests contained in SPSS PASW version 20( ). <> For test‐retest reliability and validity estimation, psychologists generally use Pearson correlations to express the magnitude of relationships between attributes. ~> number of points that Y changes, on average, for each one point change in X. SPSS calls a the “constant.” The slope is given in the “B” column to the right of the name of the X variable. VALIDITY Test-Retest Split-Half Inter-rater Cronbach Alpha . The alternative forms technique to estimate reliability is similar to the test retest method, except that different measures of a behaviour (rather than the same measure) are collected at … 2 0 obj validity; thus contributing to the overall construct validity. A simple search for “SPSS tutorials” on Google will yield a host of useful resources. In analyzing the data, you want to ensure that these questions (q1 through q5) all reliably measure the same latent variable (i.e., job motivation).To test the internal consistency, you can run the Cronbach's alpha test using the reliability command in SPSS, as follows: Cronbach’s alpha is a test reliability technique that requires only a Small values (less than 0.05) of the significance level indicate that a … SPSS provides two key pieces of information in the output viewer. using SPSS y Chapman & Ha/CRC ... assume responsibility for the validity of all materials or for the consequences of their use. 3.

In psychology, discriminant validity tests whether concepts or measurements that are not supposed to be related are actually unrelated.. Campbell and Fiske (1959) introduced the concept of discriminant validity within their discussion on evaluating test validity.They stressed the importance of using both discriminant and convergent validation techniques when assessing new tests. 1 0 obj Internal consistency and reliability were measured using Cronbach’s alpha.
