Suppose the p-value for a right-tailed test is .0245. a. What would be your conclusion at the .05 level of significance? b. What would the p-value have been if it were a two-tailed test? Calculate both the test statistic and p-value for each sample. State the conclusion for the...
A p-value, or probability value, is a number describing the likelihood of obtaining the observed data under thenull hypothesisof a statistical test. The p-value serves as an alternative to rejection points to provide the smallest level of significance at which the null hypothesis would be reject...

A simple introduction to statistical significance. Learn to differentiate between chance and factors of interest
Researchers use a measurement known as thep-valueto determine statistical significance; if the p-value falls below the significance level, then the result is statistically significant. The p-value is a function of the means and standard deviations of the data samples. ...
An initial step in the matching procedure is to calculate the probability of participating in IMF-supported programs conditional on observable economic and political conditions, estimated via a probit model.Footnote 4 The next step entails generating matches of similar probabilities, or propensity scores...
Understanding the concept of Customer Acquisition Cost (CAC) and its proper calculation is really important for businesses striving to refine their marketing strategies. Here I have given some of the examples that demonstrate the methodologies companies from different industries employ to calculate CAC an...
When it comes to analyzing data, P-value is an essential concept that helps to determine the significance of the results obtained from regression or correlation analysis. However, calculating P-value manually can be a daunting task, with a high probabili
Those appearing in two out of the three categories are designated ‘Class B’, representing a moderate level of significance. Items falling into only one of the three categories are classified as ‘Class C’, denoting a lower level of importance. [Read More: Quickest Way to Perform ABC Invent...
