In thefield of statistics, data are vital. Data are the information that you collect to learn, draw conclusions, and test hypotheses. After all,statisticsis the science of learning from data. However, there are different types of variables, and they record various kinds of information. Crucially...
Compute the student’s ranks in the two subjects and compute the Spearman rank correlation. Step 1:Find the ranks for each individual subject. I used theExcel rank functionto find the ranks. If you want to rank by hand, order the scores from greatest to sm...
Example 1: Using cor() Function to Calculate Pearson Correlation In this example, I’ll illustrate how to apply the cor function to compute thePearson correlation coefficient. Have a look at the following R code and its output: cor(x, y)# Pearson correlation# [1] 0.63733 ...
Furthermore, you can also use the PERCENTRANK.INC, PERCENTRANK.EXC, PERCENTILE.INC, PERCENTILE.EXC, QUARTILE.INC and QUARTILE.EXC functions to compute the relative standing of data in Excel. Method 3 – Determining Correlation and Regression 3.1 Using SLOPE, INTERCEPT, and STYEX Functions The STY...

How to pass multiple values from child widow In this post, I will try to explain a hack of returning multiple values from child window...So indirectly we are actually returning multiple values which are bind to an object and we return this...In this child dialog box, user will en...
How to Use VIFs: Compute VIFs for Each Predictor Variable: Statistical software can calculate VIF values for all predictors in your regression model. Assess the VIF Values: VIF = 1: Indicates no correlation with other predictors. VIF between 1 and 5: ...
Stata's power command has several methods implemented that allow us to compute power or sample size for tests on means, proportions, variances, regression slopes, case-control analysis, and survival analysis, among others. For those complicated models that are not directly supported by the power ...
I'm teaching statistics using Excel.I want to compute some descriptive statistic, for instance, the first quartile. The following data shows sex (male of...
confident that you know what that true proportion is. These confidence interval techniques can be applied to find the exact confidence interval of a mean in R, calculate confidence interval from a p value, or even compute an exact confidence interval for variance in R from a sampling ...
