In an unpaired samples t-test with sample sizes n1= 11 and n2= 11, the value of tabulated
t should be obtained for:
Answers
Answer:
20 degrees of freedom.
Concept:
An unpaired t-test is used to compare two population means. The following notation will be used throughout this leaflet:
Group Sample size Sample mean Sample standard deviation
1 n1 x1 s1
2 n2 x2 s2
Given:
Sample size, n₁ = 11
Sample size, n₂ = 11
Find:
The value of degrees of freedom for which the value of tabulated t should be obtained.
Solution:
We have the formula for calculating degrees of freedom as follows,
Degrees of freedom = n₁ + n₂ - 2
= 11 + 11 - 2
= 22 - 2
= 20
Hence, the value of tabulated t should be obtained for 20 degrees of freedom.

Answer:
20 levels of freedom.
Step-by-step explanation:
Concept:
Random t-tests are used to compare two human models. The following will be used throughout the tract:
Group Sample size Sample means the standard deviation of the sample
1 n1 x1 s1
2 n2 x2 s2
Given:
Sample size, n₁ = 11
Sample size, n₂ = 11
We have the formula for calculating degrees of freedom as follows,
Degrees of freedom = n₁ + n₂ - 2
= 11 + 11 - 2
= 22 - 2
= 20
Therefore, the table value of t should be obtained by 20 degrees of freedom.
