**Compute Degrees of Freedom for t-test comparing means of**

the degrees of freedom of t is \(n_1 + n_2 - 2\). Example: Comparing Packing Machines, cont'd Continuing from the previous example, give a 99% confidence interval for the difference between the mean time it takes the new machine to pack ten cartons and the mean time it takes the present machine to pack ten cartons.... The calculated t value is then compared to the critical t value from the t distribution table with degrees of freedom df = n - 1 and chosen confidence level. If the calculated t value > critical t value, then we reject the null hypothesis.

Step 2: test statistic is given in last line of output as t = 6.15, degrees of freedom given as 37. Unpooled methods are applied since the comparison of the largest to smallest sample standard deviation is > 2 ----- 47.7 / 22.3 = 2.14... The term degrees of freedom (df) is used in connection with various test statistics but its meaning varies from one statistical test to the next. Some tests do not have degrees of freedom associated with the test statistic (e.g., Fisher's Exact Test or the z test). When we do a z test, the z value we calculate based on our data can be interpreted based on a single table of critical z values

**If I have to find the degree of freedom for a two tailed t**

Degrees of freedom are often used with critical value tables to interpret a test's results Degrees of freedom are used in calculating the standard deviation of a data set The equation for degrees how to know cup size Step 2: test statistic is given in last line of output as t = 6.15, degrees of freedom given as 37. Unpooled methods are applied since the comparison of the largest to smallest sample standard deviation is > 2 ----- 47.7 / 22.3 = 2.14

## How To Find Degree Of Freedom For T Test

30/10/2010 · degrees of freedom are not affected by the direction of the test. df is a function of sample size. What is held constatn if the area of accepting or rejecting the sample statistics.

- A test used for comparison of two means is t-test in statistics. The formula to find the degrees of freedom varies dependent on the type of test. For a one sample T test, DOF is the number of values in sequence 1 minus one.
- Of course, the value of t 0.05 depends on the number of degrees of freedom. For example, with 2 degrees of freedom, t 0.05 is equal to 2.92; but with 20 degrees of freedom, t 0.05 is equal to 1.725.
- If necessary, Minitab truncates the degrees of freedom to an integer, which is a more conservative approach than rounding. Equal variances. When you assume equal variances, the test statistic degrees of freedom …
