Doing a project on heterogeneity I found this very useful. Appreciate you

Thank you so much. I have a question. As per the formula for I2 that you mentioned at the beginning of the video, if we insert the values of Q and df from the example at the end of the video, the I2 comes out as 18% or 0.18. However, in the example, it says I2=0.23. Can you pls explain?
