Probability Question

Question

An article reports that men over 6 feet tall earn more than men under 6 feet, with these numbers: average 6 foot plus male’s salary $55,000, average male’s salary under 6 foot tall of $47,000, with a p-value of 0.45. Based on that reported p-value, and using the common definition of "statistical significance," which is the case?

With that p value, the differences are very close, but not statistically significant

OR

With that p value, the results are not significant. 

OR

Something else.

Answer 1

Hello Gina, thank you for your question!

This p-value would indicate that it’s not statistically significant … typically you are looking for the p-value to be below 0.05 in order to indicate significance. Since 0.45 is much larger than 0.05 this would indicate that the results are not significant.

Feel free to shoot me a message if you have any questions beyond that! :)
