Enter the formula to calculate the 3rd quartile (Q3) given below: =QUARTILE($C$5:$C$16,3) Step 3: Determine the IQR, which is the Inter-Quartile Range (it represents 50% of the given data from a range of data sets that fall into the first and third quartiles) by subtracting Q1...
Apply the following formula to cell H8. =PERCENTILE.EXC(C5:C131,0.75)-PERCENTILE.EXC(C5:C131,0.25) We will use this IQR to calculate bandwidth in Silverman’s Rule. iv. Use Silverman’s Rule for Bandwidth =0.9*MIN(H7,H8/1.34)*H5^(-1/5) Based on this bandwidth, the kernel dens...
Below is the steps recommended to calculate the IQR in Excel. To calculate the Q1 in Excel, click on an empty cell and type ‘=QUARTILE(array, 1)‘. Replace the ‘array‘ part with the data of interest. For this, simply click and drag on the cells containing all of the data. The ...
