Data file – key in data
Key in the values
Copy and paste to all values column..
Missing value Data in complete- put the numbers that not uses in values –
For age- use 99 ( make sure they no use the number)

Alpha N of Items
.866 5
Good if more than 0.6
IF LESS THAN 0.6
See biggest value item at Cronbach’s Alpha item deleted -> delete that item -> analysis back
Alpha conbach= less than 0.6
Look at item statitics = deleted item with worse value
Validity boleh mengukur bahan yg diukur menggunakan instrument yg betul
Explanatory Factor Analysis = EFAPerbezaan dua pengukur yg hampir sama eg: stress and anxiety
Not confirm

SOBEL TEST Mediation
No signification for small simple size
Test 5
- Install directly to computer
To get numbers
1. Run a regression analysis with the IV predicting the mediator. This will give a and sa.2. Run a regression analysis with the IV and mediator predicting the DV. This will give b and sb.
Note that sa and sb should never be negative.
To conduct the Sobel test
Details can be found in Baron and Kenny (1986), Sobel (1982), Goodman (1960), and MacKinnon, Warsi, and Dwyer (1995). Insert the a, b, sa, and sb into the cells below and this program will calculate the critical ratio as a test of whether the indirect effect of the IV on the DV via the mediator is significantly different from zero.
Input: Test statistic: Std. Error: p-value:
a Sobel test:
b Aroian test:
sa Goodman test:
sb
Alternatively, you can insert ta and tb into the cells below, where ta and tb are the t-test statistics for the difference between the a and b coefficients and zero. Results should be identical to the first test,
except for error due to rounding.

Significant = if not content 0
Content zero if value = -ve and +ve
Result = 95% confident interval
Lower level = 0.04
Upper level = 0.03
Both positive value level = so it significant
Report = (95 % confident interval [CI], lower level, 0.04, upper level 0.03)
