Undestanding p-value and '***'
I have a dilemma regarding significance in r. I don't really understand something. For example if I have:
Does it show a significant relationship? Because the p-value seems to be greater than 0.05, but actually there are "***". Hope you can make me understand that. I'am not that familiar with [Tag:R,] I used to work with SPSS, it wasn't actually like here. Thanks!
Solution
By default R uses the scientific notation. For example, p-value of 0.05 will be represented as 5e-2 (you can type it in console).
You can change the default by typing options(scipen = 999).
In addition, you can set the number of digits to round automatically using options(digits = 3).
