The results of an independent-samples t test were t(19) = 4.02, p < 0.05. The sample size is 19.
The independent t-test is a defined as an statistical test in order to determine if we have statistically significant difference between the means of two unrelated groups.
Effect size is defined as a "quantitative measure of the magnitude of the experimenter effect" So, If we have a high value for the effect size then we can conclude that we have a stronger relationship between two variables.
T test is used to compare group means is one of the most common tests and is used to determine whether the means of two groups are equal to each other.
We perform one sample z-test;
One sample z-test is performed if the sample size is large enough (n > 30) and we want to know if the sample comes from the specific population.
The results of an independent-samples t test were t(19) = 4.02, p < 0.05. In this example,
The sample size is 19.
