Question
I took a survey and found the correlation and confidence intervals. I am having trouble interpreting them though. Can someone please help me. The survey was about job performance in the workplace and these are the numbers comparing "Communication Skills" with "Task Performance" "Citizenship Behavior" and "Coutnerproductive Behavior"
Correlations w/ communication skills:
Task Performance
Citizenship Behavior
Counterproductive Behavior
Communication skill
0.53
0.70
-0.31
Confidence Intervals w/ communication skills:
Task Performance
Citizenship Behavior
Counterproductive Behavior
Communication skill
(.26,.80)
(.43,.97)
(-.58,-.04)
please help me to explain in an easy to understand way!
Task Performance
Citizenship Behavior
Counterproductive Behavior
Communication skill
0.53
0.70

Explanation / Answer
This is how to interpret the 2 tables:
When you see the corrlation tables, you may interpret the values as:
1. descent positive correlation between Comm. skills and Task performance
2. Strong positive correaltion between Comm. skills and Citizen Behavior
3. Weak negative corrlation between Counterproductive and COmm. Skills
A positive correlation says that the 2 variables will move in the same direcvtion. The strenght is denoted by the magnitude. So, relation between task and comm. sills is higher than commskills and citizen behavior.
When you see the confidence intervals, see the width of them. Higher they are more is the sway of true estimate. You can clearly see the correlations don't change signs in the confidence intervals. Also, intervals width is same for every correlation i.e. .27 points ( .54/2),
