How Do You Find The 1st Quartile Of A Set Of Data? First Quartile(Q1) = ((n + 1)/4)t h Term. Second Quartile(Q2) = ((n + 1)/2)t h Term. Third Quartile(Q3) = (3(n + 1)/4)t h Term. How do you calculate Q1 and Q3? Q1 is the median (the middle) of the lower half of the
How Do You Find Outliers? Multiplying the interquartile range (IQR) by 1.5 will give us a way to determine whether a certain value is an outlier. If we subtract 1.5 x IQR from the first quartile, any data values that are less than this number are considered outliers. What is the formula for finding outliers?
