There are different formulas to find the mean of a given set of data, as given below, For ungrouped data, mean, x̄ = (sum of observations) ÷ (number of observations) For grouped data, mean, x̄ = Σfx/Σf where, f = frequency of each class ...
It is the measure of Central Tendency other than Mean and Median. The mode can easily be found for a finite set of data or observations. We can find the mode of data with normal data set, group data set and non-grouped or ungrouped data set. However, the formula to find the mode ...
Ungrouped Data Population Variance = ∑(Xi−¯¯¯¯¯X)2n∑(Xi−X¯)2nwhere, ¯¯¯¯¯XX¯ stands for mean, MiMi is the midpoint of the ith interval, XiXi is the ith data point, N is the summation of all frequencies and n is the number of observations....
The formula to calculate mean deviation for the given data set is provided below:Mean Deviation \( = \frac{{\sum \left| {x – \mu } \right|}}{N}\)Here, \(\sum \) denotes the sum of the values \(x\) denotes each value in the data set\(\mu \) denotes the mean value of ...
2.How can we calculate the mode of ungrouped data? Ungrouped data modes can be found by selecting the most common item in the data. 3.What do you mean by central tendency? Central tendency measurements describe a data set by identifying the centre position in the data set as a single rep...

Deciles are used in the investment field to assess the performance of aportfolioor a group ofmutual funds. The decile rank acts as a comparative number that measures the performance of anassetagainst similar assets. For example, if an analyst is evaluating the performance of a set of mutual ...
Mean, median, and mode reveal different aspects of your data. Anyone will give you a general idea, but may mislead you; having all three will give you a more complete picture For a normal distribution the mode, mean, median have the same value since Mode is a normal distribution. Analyzin...
Mode is defined as the value which occurs most frequently in a data set. (a) For Ungrouped or Raw Data: (b) Mode for Continuous data (d) Graphi
