So in the ocr MEI exam will you be expected to use the sx value in your calculator rather than the original one to find your answer?

Hi Sir, you got different answers by using the quartiles method compared to using the mean and standard deviation, so which is the correct answer? the outliers were different.
Thanks.

How would the mean and standard deviation be affected in removing outliers?

Would you still get the marks if you used the calculator to get the values (mean and standard deviations)?

Hi sir, so is the data on the left discrete data and then the grouped data on the right would always be continuous data?

Would it be possible to prove an outlier if the information you have been given is the range 50 and standard deviation 9. I have no clue lol
