Question

Alpha value = .57	Alpha if item deleted
Home life satisfaction	.51
Work life satisfaction	.57
Relationship satisfaction	.42
Salary	.82

Acceptable Reliability? It is not
What items Should be Removed?

Explain:

Answer 1

Solution:

A general accepted rule is that α of 0.6-0.7 indicates an acceptable level of reliability, and 0.8 or greater a very good level. However, values higher than 0.95 are not necessarily good, since they might be an indication of redundance

Here Alpha value is = 0.57 hence reliability is not acceptable.

Cronbach alpha (often called coefficient alpha) is a measure of internal consistency reliability. It measures how consistent respondents are when they respond to the items. The highest score is 1, meaning perfect consistency/reliability. Scores above .7 are desirable and scores above .9 show strong reliability.

Her we can see that only variable salary have alpha value 0.82 greater than 0.7 hence we can not remove Salary.

But remaining variable and there alpha values

Home life satisfaction = 0.51

Work life satisfaction = 0.57

Relationship satisfaction = 0.42

Hence all alpha values are less than 0.7 hence we drop all three variables Home life satisfaction,Work life satisfaction and relationship satisfaction .
