Joshua conducted an independent samples t-test and found t(20) = 10.25, p < .05. he then calculated his effect size and obtained a value of d = 0.05. what should joshua say in the reports on his results?

On this case since the p value is less than 0.05 then the results are significant. So then Joshua can say that the t-test conducted is significant. And on this case makes sense report the effect size.
Step-by-step explanation:
Effect size is defined as a "quantitative measure of the magnitude of the experimenter effect". 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.
The independent t-test, is an statistical test in order to determine if we have statistically significant difference between the means of two unrelated groups.
We can check for example the following hypothesis:
Null hypothesis:![\mu_{1} \leq \mu_{2}](/tpl/images/0407/2348/dc5be.png)
Alternative hypothesis:![\mu_{1} \mu_{2}](/tpl/images/0407/2348/9ea25.png)
The statistic for this test is given by:
The value obtained after apply the formula (1) was 10.25.
And the degreed of freedom are calculated from:
On this case since the p value is less than 0.05 then the results are significant. So then Joshua can say that the t-test conducted is significant. And on this case makes sense report the effect size.
Usually when the Cohen effect size value d=0.2 or lower we can consider this as a 'small' effect size, and that's our case.
