This calculator will compute the 99%, 95%, and 90% confidence intervals for an R2 value (i.e., a squared multiple correlation), given the value of the R-square, the number of predictors in the model, and the total sample size.
Confidence interval for an R2value: whereR2is the squared multiple correlation,αis the desired confidence interval percentage,SER2is the standard error forR2,tis a t-value,kis the number of predictors in the model, andnis the total sample size. Standard error for an R2value (Olkin and Finn...
Given the parameters of the population proportion distribution andsample standard deviation, generate the bootstrapconfidence interval. In this situation, we’re basically using r like an error interval calculator… Using the 95 percent confidence level and confidence coefficient function, we will now cr...
Notice that the group means match your calculation from the previous question. And this command provides a confidence interval for the difference between the groups. Include the test of the difference in proportion in your document. Add a title of as Exhibit 2 Race and Gender Relationship. I cl...
