I use R for programming but when I use the summary function on a regression, there is one parameter that is Std. Error, which I don't understand. What is it?

    I suggest you get yourself a basic textbook on regression. Googling "standard error of regression coefficients" should also yield some useful results. – Roland Nov 11 '19 at 08:29

    For what a standard error is, see [here](https://en.wikipedia.org/wiki/Standard_error). In this case you're dealing with the standard error of the coefficient estimate (i.e. of the intercept or slope, respectively) – Glen_b Nov 11 '19 at 08:38

    It is an estimate of the scale of uncertainty in the coefficients. https://stats.stackexchange.com/questions/85943/how-to-derive-the-standard-error-of-linear-regression-coefficient shows how it is calcuated – Henry Nov 11 '19 at 08:38
