It is given that the correlation coefficient is 0.52.
From the correlation coefficient table, it follows;
Coefficient 0.9 to 1.00 is very high positive.
Coefficient 0.7 to 0.9 is strong positive.
Coefficient 0.5 to 0.7 is moderately positive.
Hence the value 0.52 lies between 0.5 to 0.7.
So it is moderate positive correlation.
Fourth option is correct.
