I have F value, df, sum of squares, mean squares but neither sample size of control group and experimental group nor mean for control and experimental group. Could you please advice me how to insert data in comprehensive meta-analysis?
You can calculate the effect size without sample size, but I would argue that you cannot do a meta-analysis without it. This is because the result of the meta-analysis is a weighted d, meaning it takes into account the number of participants. Shortly put, the average of two effect sizes, 0.1 and 0.3, is 0.2. But say that the 0.3 effect size was based on an N of 2000, while the first was an N of 10, then one has more weight than the other, and the "average" would be closer to 0.3 than 0.2.
I may be wrong, but you should be able to calculate effect sizes with the data you report, but you cannot conduct a comprehensive meta-analysis without knowing the N of both the control and experimental group. Or, you could, but it wouldn't be weighted.
@Esen ,,,,, Thanks a lot for your answer. I know effect size can be calculated using the above data but I want to conduct met-analysis which seems to me not possible....Thanks again
@Harsh I know the manual......the problem is that the study has not mentioned sample size
