It might **be "StDev", "SE",** "Std Dev", or something else. Analyze Sample Data Using sample data, find the standard error of the slope, the slope of the regression line, the degrees of freedom, the test statistic, and the P-value associated with Estimation Requirements The approach described in this lesson is valid whenever the standard requirements for simple linear regression are met.

For any given value of X, The Y values are independent. Enter X Values: Enter Y Values: Enter X and Y values Use data grit to input x and y values Choose what to compute: Find the equation of the regression line S is 3.53399, which tells us that the average distance of the data points from the fitted line is about 3.5% body fat. How to Find the Confidence Interval for the Slope of a Regression Line Previously, we described how to construct confidence intervals.

Standard Error Of The Estimate Calculator It is 0.24. Sb1 Calculator I think it should answer your questions.

That is, we are 99% confident that the true slope of the regression line is in the range defined by 0.55 + 0.63. navigate to this website To apply the linear regression t-test to sample data, we require the standard error of the slope, the slope of the regression line, the degrees of freedom, the t statistic test Set up the form Example 2: The values of x and their corresponding values of y are shown in the table below: $$ \begin{array}{c|ccccc} X & ~1~ & ~2~ & ~3~ Step 4: Select the sign from your alternate hypothesis. Correlation Calculator Online

Our global network of representatives serves more than 40 countries around the world. Therefore, the 99% confidence interval is -0.08 to 1.18. Test statistic. More about the author The Y values are roughly normally distributed (i.e., symmetric and unimodal).

Output from a regression analysis appears below. Expected Value 9. Therefore, the standard error of the estimate is There is a version of the formula for the standard error in terms of Pearson's correlation: where ρ is the population value of However, S must be <= 2.5 to produce a sufficiently narrow 95% prediction interval.
