Reliability=coefficient correlation= alpha= biasa nak 0.75 hinggga 0.9 highly reliable

Validity ada dua jenis:
1.convergent
2.discriminant

Cuba lihat scree plot adakah negative atau posotif
Jika positive mean ada hubungan antara variable yang cuba dihubungkan mean directly relationship
Jika negative mean investly relationship

Nilai validity kita rujuk kepada nilai standard error…jika SE tinggi mean tidak valid…low validity
Content validity describes a judgment of how adequately a test samples behaviour representative of the universe of behaviour that the test was designed to sample. (Cohen & Swerdlik, 2005).
Standard Error of Estimate






Assuming SD = 10 and criterion-related validity = .36








Jika SE rendah mean high validity

Jika SD tinggi biasanya SE jua tinggi…

P<0.05.... mean 95% ada significant relationship...mean highly reliability relationship between the variable
P<0.01...mean 99% ada significant relationship...mean highly significant relationship between the variables


Jika dua categories (biasanya variable…kita pakai T test…atau Chi Square

Jika tiga (>2…categories / variable yang kita measure…maka kita pakai ANOVA untuk analisa

Kita harus buat hipothesis (andaian kajian kita berdasarkan fakta researcher yang lalu…

15 tahun lalu kita pakai hypothesis null dan hypothesis alternative
Kini kita pakai
