Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following methods serves to measure the correlation between two variables?
A
Scatter diagram
B
Frequency distribution
C
Two-way table
D
Coefficient of rank correlation
Explanation: 

Detailed explanation-1: -Karl pearson’s coefficient of correlation determines how strongly the two variables are related to each other i.e. measure the linear correlation between the variables.

Detailed explanation-2: -Correlation can be measured through three different methods; viz., Scatter Diagram, Karl Pearson’s Coefficient of Correlation, and Spearman’s Rank Correlation Coefficient.

Detailed explanation-3: -Pearson. The Pearson product-moment correlation coefficient, also known as r, R, or Pearson’s r, is a measure of the strength and direction of the linear relationship between two variables that is defined as the covariance of the variables divided by the product of their standard deviations.

Detailed explanation-4: -The correlation coefficient is determined by dividing the covariance by the product of the two variables’ standard deviations. Standard deviation is a measure of the dispersion of data from its average. Covariance is a measure of how two variables change together.

Detailed explanation-5: -There are three types of correlation: Positive and negative correlation. Linear and non-linear correlation. Simple, multiple, and partial correlation.
