The treatment of the text values remain the same as with =VARA() and =VARPA() functions. The function for sample variance is =STDEVA() and the function for population variance is =STDEVPA(), if the text values are to be counted. Standard deviation can also be computed on logical strings, and text, just like variance. Older versions of Excel support =STDEV() for sample standard deviation, and =STDEVP() for population standard deviation. Similar to variance, Excel offers two functions, =STDEV.S() for sample standard deviation, and =STDEV.P() for population standard deviation. Naturally, if the variance computation is different for a sample and for a population, the standard deviation would be different as well. We already know that the standard deviation is nothing but the square root of variance. Any text value is counted, and is treated as 0.Logical values such as TRUE and FALSE are counted, and treated as 1, and 0, respectively. =VARA() and =VARPA() can handle the following text strings that =VAR.S() and =VAR.P() ignore: These differ from the other variance functions in how they treat certain text strings within the data. Microsoft Excel also supports two other functions that calculate variance, =VARA() for sample variance, and =VARPA() for population variance. Older versions of Excel used =VARP() and =VARS() to calculate population variance, and sample variance, respectively. If we treat our data as a sample, the variance for Arun is 1189.58, and the variance for John is 50. If we treat our data set as the population, then the variance for Arun is 1275, and the variance for John is 162.5. This change is taken care of by Excel with two different functions: =VAR.P() for population variance, and =VAR.S() for sample variance. However, when we compute the variance for a sample, we divide the sum of squared deviations by (n-1). When we are computing the variance for a population, we divide the sum of squared deviations by n. We have already seen that variance is nothing but the average of the squared deviations. The calculation of variance differs slightly depending on whether the data set describes a sample or the entire population. The higher the value of the range, the greater is the spread of the data. The difference between the two is the range. The =MAX() and =MIN() functions would find the maximum and the minimum points in the data. The formula would be =MAX()-MIN() where the dataset would be the referenced in both the parentheses. However, we can easily compute it by subtracting the minimum value from the maximum value. We can use the same logic to aggregate values on other level.Excel does not offer a function to compute range. but there is no inbuilt formula to calculate Median or Quartile with multiple conditions. There are few formulas available to aggregate for multiple conditions like IFS, AVERAGEIFS, COUNTIFS, MAXIFS, MINIFS, SUMIFS etc. So it is MEDIAN IFs and QUARTILE IFs but there is no direct formula we’ll create one. I’ve attached the Excel workbook for download and reuse. Hello friends!! today we’ll be learning how to calculate Median and Quartile values with multiple conditions.
