WebJan 22, 2024 · To test if the slope coefficient is statistically significant, we can calculate the t-test statistic as: t = b 1 / se(b 1) t = 2.7037 / 0.7456; t = 3.626; The p-value that corresponds to this t-test statistic is shown in the column called Pr(> t ) in the output. The p-value turns out to be 0.00464. WebMay 24, 2024 · The standard error of the mean is the variability of sample means in a sampling distribution of means.

WebSep 30, 2024 · The standard error measures the dispersion of the distribution. As the sample size gets larger, the dispersion gets smaller, and the mean of the distribution is closer to the population mean ( Central Limit Theory ). Thus, the sample size is negatively correlated with the standard error of a sample. WebSep 10, 2024 · The standard error tells you how far your sample statistic (like the sample mean) deviates from the actual population mean. The larger your sample size, the smaller the SE. In other words, the larger your sample size, the closer your sample mean is to the actual population mean. To know more about Standard Error (SE) please do watch below …
