Help Average

[Trident_muh]

Lets say sample-1 has an average value same goes with sample-2, sample-3 and sample-4. but each of them has different average value. how can i get the overall value of all the sample?

To calculate the overall value of all the samples, you need to consider the average value of each sample and the size of each sample.

Here's a step-by-step process to calculate the overall value:

1. Determine the average value of each sample: Calculate the average of sample-1, sample-2, sample-3, and sample-4. Let's denote them as "avg1", "avg2", "avg3", and "avg4", respectively.

2. Determine the size of each sample: Determine the number of observations or elements in each sample. Let's denote the sizes as "size1", "size2", "size3", and "size4", respectively.

3. Multiply each average value by the corresponding sample size: Multiply "avg1" by "size1", "avg2" by "size2", "avg3" by "size3", and "avg4" by "size4".

4. Sum up the results from step 3: Add the results obtained in step 3 to get the total value.

Mathematically, the overall value can be calculated using the following formula:

Overall Value = (avg1 * size1) + (avg2 * size2) + (avg3 * size3) + (avg4 * size4)

By following these steps, you can obtain the overall value of all the samples, considering their respective average values and sizes.

Another example. each of the sample have their own average value. now how can i get the overall average?
Sample-1: 124
Sample-2: 564
Sample-3: 54
Sample-4: 943
