For the standard error of the mean, the value indicates how far sample means are likely to fall from the population mean using the original measurement units. Again, larger values correspond to wider distributions. For a SEM of 3, we know that the typical difference between a sample mean and...

The standard error of the mean is calculated using the standard deviation and the sample size. From the formula, you’ll see that the sample size is inversely proportional to the standard error. This means that the larger the sample, the smaller the standard error, because the sample statistic...
When several random samples are extracted from a population, the standard error of the mean is essentially the standard deviation of different sample means from the population mean. However, multiple samples may not always be available to the statistician. Fortunately, the standard error of the mean...
and also reports an average income of $5,000. Because their sample size is smaller, their SEM will likely be larger (let's say, $200). This means their $5,000 average is less reliable than yours. There's a wider range of uncertainty around their estimate of the true population mean...
