Evaluation Of Exploratory Factor Analysis Essay

The alpha reliabilities for the general occupational themes section were between .90 and .94. This section also had a high test-retest reliability of .84 to .92. The test-retest reliability for the third section, basic interest scales, was also high at between .80 to .94. Overall, the Strong Interest Inventory has very high reliability which makes it a very good test.

5. I thought the researchers’ use of multiple scales was very helpful to provide more evidence. In psychology, we are testing for ideas or concepts that are not observable. It’s important to rely on more than one type of research to capture these changes in scores or perception. It also gave the study a higher chance of showing a significant difference.

There is no specific section discussing reliability and validity in this study. Although there was no specific section or heading, throughout this study, the authors did consult with the advisory committee at multiple points and the authors do lists that as a limitation that this study is not generalizable. Main findings were also discussed and verified with the community advisory committee for accuracy of

The study tools were applied on the study sample after ensuring their validity and reliability, and these tools are :

The basic analysis used for reliability analysis is to find the Cronbach Alpha (α) value. There may be a single α value for each item, or an α value for all questions. The α value obtained for all the questions indicates the total reliability of the questionnaire and is expected to be greater than 0.7, the lower α values indicate that the questionnaire has poor reliability, and α> 0.8 indicates that the questionnaire has high reliability. In our study, we calculate 0.846 which means that our items is "good" and reliable. After all, we found the overall score by collecting all items. See Appendix

Commonly identified are a) reliability - which indicates the tests ability to measure the construct of interest consistently and b) validity – indicating how well the test accurately measures the construct of interest.  Reliability can be further analyzed as Test-Retest Reliability, Internal Consistency, Intra-rater Reliability Inter-rater Reliability, while Validity can be analyzed as Face Validity Content Validity Criterion Validity. The validity of the following tests are established by the correlation of the results to other tests such as MMPI, and

In order to test the construct validity of each scale, bivariate correlation will be used, because this test is to find out the association among those different variables and how strong the association is. (Pallant,2010). At the same time, checking the association among the subscales is regarded as way to assess scale’s construct validity (ibid). In addition, most of the researchers believe that the dividing point of the statistical significance (p) to ensure the relationship between variables is .05. Namely, in 100 samples, there are 5 times chances to get relationship that are not appeared in the whole population. Specifically, p < 0.05 is set to ensure the expected relationship (Bryman and Bell, 2007). And all the

2003 analyzed the test items as a whole with a Rasch analysis. They also analyzed the three subtests individually with Cronbach’s alpha, and then explored the verbal, numerical, and figural content of each subtest using a multidimensional random-coefficients multinomial logit model (Sternberg, et al., 2006). These analyses demonstrated that the STAT works best as a three-factor, between item model (analytical, practical, creative), as opposed to a one-factor model (Sternberg, et al., 2006). Furthermore, Sternberg et al. 2006 also demonstrated that a three-factor model (verbal, numerical, figural), within each subtest was only necessary for the analytical subtest. That being said, reliability measures of the three subtests were not high. Measures of .67, .56, and .72 for analytical, practical, and creative subtests, respectively, were provided (Sternberg et al., 2006). Moreover, the Rasch analysis of the STAT, as a whole, were slightly

This construct is evaluated by 4 items using a 5-point Likert-type scale ranking responses from “not at all” (1) to “a lot” (5).

Is established when Cronbach’s Alpha, enables an indication of items that are related and to create a new category within. Then that new category’s internal consistency is measured and

“Now We Can Begin” an essay by Crystal Eastman is a very powerful essay. Eastman makes the point know in her essay that an honest and true feminist no matter where she stands in the movement she will see to the woman’s fight with strength and courage and how it  matters in the future and as well as its difference in its approach for the workers fight for industrial freedom. Eastman state “In fighting for the right to vote most women have tried to be either non-committal or thoroughly respectable on every other subject. Now they can say what they are really after; and what they are after, in common with all the rest of the struggling world, is freedom”

The atomic bombs that were dropped on Japan in 1945 were not seen as a logical reaction to the war by everyone. Leo Szilard was a Hungarian physicist that was the first to conceive of the mechanics of the atomic bomb, and how it worked. He was fighting the use of these bombs on Japan, and trying to urge the President to reconsider the idea. Although he lost the argument over whether to use the bombs, his argument was valid based on the devastation that was caused by the atomic bombs in Japan. Given the results of the devastation in Japan, his side of the argument is unmistakably seen.

Main concern of the research is the little variation of all critical factors ranging from 3.64 to 6.00 (lowest to highest mean) on the seven-point scale and it appears that the majority of factors are of high importance. Still Psomas, et al. (2010, p. 447) attempt to group factors into differentiated importance
