After all, you know the IQR has some benefits. This time, you go to SPSS and select Analyze > Descriptives > Frequencies. You put the age variable in the "variables" box and then click Statistics. Make sure Quartiles, Mean, Median, Mode, Range, Standard Deviation, and Variance are checked (because it never hurts to get lots of information :). You click continue, then ok.Using the Percentiles that are reported in the output (these are equivalent to Q1, Q2, and Q3), you are able to determine that the interquartile range for the "age" variable is: Group of answer choices 35 20 22 23.29 24 4

Please explain how to find the mean for a frequency with and without statcrunch and excel. It is not allowing me to upload or copy and paste my question and it is quite lenghty
