mediation

http://ripl.faculty.asu.edu/mediation/ http://www.public.asu.edu/~davidpm/classes/psy536/Baron.pdf See page 1173, 1174 and 1178 the justification for a mediator is very very different compared to the justification of a moderator. Also in moderator also there are two types of issue we are looking at 1. Change Direction or 2. Change Strength of relationship. Allow the investigation of the plausibility of "third-variable explanations" for the results of past studies. When there is "inconsistency" you are looking for a possible "moderator" and when there is "consistency" you are looking for a "mediator" (mechanism).

sample size for sem

there is no magic number for SEM analysis. It all depends on complexity of your model and data quality (ie; loadings). Hair et al. (2010) mentioned that with good loadings even with 75 you can get a good model fit but with low loadings you may need more than 500. You may wnt to read the article by Reinartz et al. (2009) "The well-known rule of thumb that ML-based CBSEM requires at least 200 observations to avoid problems of  non-convergence and improper solutions emerged from this prior work. On the basis of our findings, we confirm that this rule is true on average but that wide variations depend on indicator loadings. Based on our analysis, the minimum sample size ranges from as low as 100 (medium or high equal loadings) to a maximum of 500 (low equal loadings and two indicators per construct).

Thanks Prof Ramayah Thurasamy! I came across with that argument as well in article written by Lei and Wu (2007) in which it does mention that the sample size required is somewhat dependent on model complexity. Thanks Prof. Now, it is clearer.

concurrent validity

Soalan kuiz🎯🎯🎯
Siapakah di sini yg tahu/tidak tahu apa itu concurrent validity dan dlm keadaan yg bagaimana ia diperlukan?

Sbb utama concurrent validity dibuat dlm kes kita bina questionaire sendiri. Jadi utk maklumkan kpd dunia bhawa alat kita juga tidak kurang hebatnya, jd kita ambil soalan standard yg terkenal ie Skala Benci...lalu kita bandingkan Skala Benci Juma. Jd bila result dari skala Juma mempunyai direction yg sama dgn skala yg standard, jd kita blh katakan skala kita juga mirip dgn mereka. Kita juga boleh bandingkan skala yg opposite misalnya skala Suka yg standard. Jadi bagi mereka yg sgt suka bina new instrument, inilah type validity yg patut diutamakan

parapharase Dr ot

Baca jgn tak baca: Cara terbaik paraphrase adalah dgn menulis SESUKA HATI !!

Aku nak share isu “lama” ini… isu paraphrase. Jgn takut nak paraphrase sebab anda boleh lakukan sesuka hati anda saja.

Hah?

Fahami dulu dua level paraphrase… iaitu adequate dan inadequate paraphrase.

Inadequate paraphrase merujuk kepada perubahan beberapa perkataan sahaja dari perkataan asal, dan ini mesti dielakkan takut2 terjatuh kepada plagiarism.

Adequate paraphrase pula merujuk kepada pemahaman anda terhadap statement asal dan menulisnya semula dalam kontek kajian anda tanpa mengubah maksud / idea asal dalam pernyataan yang dipetik.

Katalah anda berminat dgn statement berikut:

Cognitive Load Theory suggests that learners can absorb and retain information effectively only if it is provided in such a way that it does not overload their mental capacity (Author, 2009)

1. Contoh inadequate paraphrase:
Cognitive Load Theory proposes that students can extract and hold information successfully when the information does not overload their mental ability to hold the information effectively (Author, 2009)

2. Contoh adequate paraphrase:
Cognitive Load Theory is an instructional theory that starts from the idea that student working memory is limited with respect to the amount of information it can hold. That means a learner should be encouraged to use his or her limited working memory efficiently, especially when learning a difficult task (Author, 2009).

Bezakan kedua2 contoh di atas. Contoh 1 ditulis semula dgn cara yang hampir sama dgn pernyataan asal. Ini berbeza dengan contoh 2 yang ditulis dalam kontek kajian yang dilakukan tanpa mengubah maksud asal.

Jadi asasnya adalah pemahaman menyeluruh anda terhadap pernyataan asal sebelum membuat paraphrase supaya maksud dalam pernyataan dipermudahkan untuk anda tulis semula dalam kontek kajian anda.

Jika anda faham maksud statement asal... anda paraphrase lah “sesuka hati” anda tanpa perlu takut, risau, runsing, bimbang atau ragu… lagi berbeza perkataan yang anda guna (kecuali keyword) lagi bagus... sebab reflect pemahaman anda yang mendalam.... adanya...

OT - share jgn tak share !
