The P values shown are examples. It shows one P value presented as ".033", or as "0.033", or as "0.0332" depending on the choice you made (note the difference in the number of digits and presence or absence of a leading zero). Some people have misunderstood thi...
In fact, any sample mean is an unbiased estimator for the population mean. (Here X is 1 or 0, so the average of the Xi is the proportion of Yes's.) Let's skip the derivation for now (we'll have a derivations lesson later), so we can get to the larger issues....
— Minimum N of a sample (for measuring a true mean or a proportion within a set margin of error). — Least-squares linear regression (with a scatterplot that colors outliers, and a tool to calculate a predicted y using the regression equation). — Chi-squared (which instantly calculates...

Add mean comparison p-values to a ggplot, such as box blots, dot plots and stripcharts. stat_compare_means(mapping=NULL,data=NULL,method=NULL,paired=FALSE,method.args=list(),ref.group=NULL,comparisons=NULL,hide.ns=FALSE,label.sep=", ",label=NULL,label.x.npc="left",label.y.npc="top...
As n increases, the mean of the random variable X-bar stays the same The symbol we use to represent the mean of the random variable X-bar Mu with subscript X-bar The set of all possible sample means from all possible samples of size n from the population is known as the Sampling dist...
Take the example below, it displays exactly the same p-value both for adjusted and non-adjusted: library(ggplot2) library(ggpubr) library(tidyverse) a = rnorm(mean=1, 100) b = rnorm(mean=1.5, 100) data = rbind_all(list( data.frame(facet=1, group="A", value=a), data.frame(face...

Hospital pharmacists have a higher mean rank (25227) than community pharmacists (independent 16630, chain 13801, p<0.005). This superior knowledge is reflected in their counseling practice, with hospital pharmacists having a mean rank of 22290, exceeding the mean ranks for independent (18883) and ...
