A sample of n = 4 scores has ss = 48. what is the estimated standard error for the sample mean?

Video Transcript

Hello. So we have a sample size four and the sum of squares to be 48. And we want to find the standard error. So the standard error that is given by the standard deviation divided by square root of n. But we don't have the standard division. So we're going to start off by getting the variants, sir, variant Is the sum of squares divided by N -1. So that's gonna be 48 divided by four minus one, That's 48/3- 16. So from that we can get our standard division, It is squared of the variance 16 And that is four. So now our standard error which is the standard deviation over that is going to be four divided by square root of our sample size for We're gonna have four divided by two. Our standard error is going to be according to. Okay, thank you very much.

How do you calculate the estimated standard error?

Steps to Calculate Standard Error Standard error is calculated by dividing the standard deviation of the sample by the square root of the sample size.

What does the estimated standard error measure quizlet?

The estimated standard error in the denominator measures how much difference is reasonable to expect between a sample mean and the population mean.

What is the standard error of the sample mean quizlet?

Standard error of the mean. Tells you how accurate your estimate of the mean is likely to be. Calculated by the standard deviation of the observations divided by the square root of the sample size.

When n is small less than 30 how does the shape of the T distribution?

For practical purposes, the shape of the t-distribution is identical to the normal distribution when sample size is large. However, when sample sizes are small (below 30 subjects), the shape of the t-distribution is flatter than that of the normal distribution, and the t-distribution has greater area under the tails.
