Spearman-Brown formula ptherwise called as split half method?
not otherwise....split half method is one way of determining reliability of your test and Spearman-Brown formula is a technique used to re-calculate the correlation of your test when you split your test items into half.... this means that the result of Spearman-Brown provides you the correlation of your test in full length.
What is the purpose of using correlation analysis How might correlation analysis be used in business decisions or in strategy formulation and implementation?
The correlation analysis is use in research to measure and interpret the strength of a logistic relationship between variables.
Can A correlation matrix can be used to assess multicollinearity between independent variables?
yes
What is the significance of using coefficient of correlation as a statistical tool of analysis?
It tells you how strong and what type of correlations two random variables or data values have. The coefficient is between -1 and 1. The value of 0 means no correlation, while -1 is a strong negative correlation and 1 is a strong positive correlation. Often a scatter plot is used to visualize this.
Spearman's rank correlation coefficient for grouped data?
Although Spearman's rank correlation coefficient puts a numerical value between the linear association between two variables, it can only be used for data that has not been grouped.

Why is there a 6 in spearman rho formula?
The number 6 in the Spearman's rank correlation coefficient formula is a constant used to standardize the formula and make it more interpretable. It helps to scale the formula so that the resulting correlation coefficient falls within the range of -1 to 1, which indicates the strength and direction of the relationship between the ranked variables. Essentially, the 6 in the formula is a mathematical adjustment that ensures the correlation coefficient is properly calculated and comparable across different data sets.
Spearman-Brown formula ptherwise called as split half method?

What graphs can you use to measure correlation?
A scatter graph can be used to establish whether or not there is correlation and to get an approximate idea as to its strength. But no graph will actually measure correlation.
What is the difference between correlation coefficient and chi square?
correlation is used when there is metric data and chi square is used when there is categorized data. sayan chakrabortty
What is meant by correlation in Digital Signal processors?
correlation is a technique of correlating two signals with each other and producing the third signal. In correlation if two different signals are used it is called cross correlation and if same signal is correlated with itself it is called as auto correlation.
Is Fisher exact test used for calculating correlation?
no
What is a correlation experiment?
Experiment used to quantify a trend
A Correlation coefficient is a number used to describe?

What does correlation tell us?
Correlation is a statistical technique that is used to measure and describe the strength and direction of the relationship between two variables.
