Step-deviation method: \(\begin{array}{l}Mean, (\overline{x})=a+h\frac{\sum f_iu_i}{\sum f_i}\end{array} \) Go through the example given below to understand how to calculate the mean for grouped data. Example: Find the mean for the following distribution. ...
for grouped data, we can calculate the mean using three different methods of formula. direct method assumed mean method step deviation method mean \(\begin{array}{l}\overline{x}=\frac{\sum_{i=1}^{n}f_ix_i}{\sum_{i=1}^{n}f_i}\end{array} \) here, ∑f i = sum of all ...
Mean is used to understand the whole data by a single number. For example, to analyze how high the students of a class are, it is enough to just find the mean instead of looking into each student's height. How To Use the Mean Formula?
Step 3: Next, we need to select the range for our mean formula in Excel in the WPS office. In our example, the range is B2:B21. WPS Mean score of class range Step 4: Let’s press “Enter” to allow WPS Office to execute the Average Function and see the results. Mean Class Scor...
Mean deviation is a statistical measure that computes the average deviation from the average value of a given data collection. Learn the mean deviation formula in detail.
Step 6: Calculate the VarianceThe variance (σ²) can be calculated using the formula: σ2=∑(fi⋅(xi−μ)2)N=392000.85500=784.00 Step 7: Calculate the Standard DeviationThe standard deviation (σ) is the square root of the variance: σ=√784.00=28.0 Final Results- Mean: 27.99- Sta...
To find the mean of 75 numbers, given that the mean of 45 of them is 18 and the mean of the remaining 30 is 13, we can follow these steps:Step 1: Calculate the sum of the first 45 numbers The mean of the first 45 numbers is giv
