Question 1.
Explain the types of correlation.
Answer:
A correlation refers to a statistical tool used to measure the relationship between two or more variables.
If the change in one variable is accompanied by a change in the other variable, this interdependence is called correlation. It is measured by correlation coefficient which extends between -1.00 to + 1.00.
The types of correlation are:
(i) Positive correlation – Both variables either increase or decrease at the same time, for e.g., extent of rehearsal (revision)↑ and recall score↑.
The value of positive correlation from 0.00 to + 1.00. It is represented as: variable 1 variable 2
(ii) Negative correlation – An increase in one variable is associated with a decrease in the other and vice-versa. The value of the correlation is between 0.00 to -1.00, for e.g., bunking of lectures (↑) and score in exams (↓).
(iii) Zero correlation – A change in one variable leads to no significant change in the other variable, for e.g., height and intelligence.
Question 2.
