Answer:
Option A ,B , C , E are true .
Explanation:
Given : Statements about correlation .
To find : Which statements is true.
Solution : We have given statement about correlation .
Correlation : When two sets of data are strongly linked together we say they have a High Correlation.
Hence, option 1 is true it show the relation between two quantity variable
Correlation can have a value:
• 1 is a perfect positive correlation .
• 0 is no correlation (the values don't seem linked at all)
• −1 is a perfect negative correlation
Since , its coefficient lies from -1 to 1.( B is true )
If r = 1 then it has strong relationship between two variable ( C is true)
If r= 0 the it has no relation ( D is false )
If r = -0.9 the it has high negative correlation ( E is true )
Therefore, Option A ,B , C , E are true .
