The formula for effect size is quite simple, and it can be derived for two populations by computing the difference between the means of the two populations and dividing the mean difference by the standard deviation based on either or both the populations. Mathematically, the formula for Effect Size represented as, θ = (μ1 – μ2) / σ

What is effect size?
The term “effect size” refers to the statistical concept that helps in determining the relationship between two variables from different data groups. In other words, the concept of effect size can be seen as the measurement of the correlation between the two groups, the standardized mean difference in our case.
Why is effect size important?
It is very important to understand the concept of effect size because it is a statistical tool that helps in quantifying the size of the difference between two groups, which can be considered to be the true measure of the significance of the difference. In other words, it is a statistical method to measure the relationship between two variables from a different group of data sets. Now, effect size enables readers to grasp the magnitude of the mean differences between two groups, while statistical significance validates that the findings are not due to chance. So, both effect size and statistical significance are essential for a comprehensive understanding of the statistical experiment. As such, it is advisable to present the effect size and the statistical significance, along with the confidence interval, as both the metric complement each other and enables better understanding.
How to find the mean of a population?
Step 1: Firstly, determine the mean of the 1 st population by adding up all the available variable in the data set and divide by the number of variables. It is denoted by μ 1. Step 2: Next, determine the mean for the 2 nd population in the same way as mentioned in step 1. It is denoted by μ 2.

What is the effective interest rate?
The term “effective interest rate” refers to the investment’s true annual yield that is earned due to the result of compounding over the period of time. Conversely, the effective interest rate can be seen as the true cost of borrowing from the point of view of a borrower.
Why is effective interest rate important?
It is important to understand the concept of an effective interest rate because it is a vital metric for an investor or another financial user. The investors tend to use the effective interest rate predominantly as it is the actual yield received from an investment. As such, the investors lay greater emphasis on the number of compounding per year as a higher number of compounding means greater yield. On the other hand, the perspective changes for a borrower who seeks a lower number of compounding per year as it would keep their interest expense low and result in better profitability.

All four depreciation functions covered in this section have three required arguments in common, as follows:
Depreciation example with first four functions
Let's go through an example using the four methods of depreciation described so far. Assume that our company has an asset with an initial cost of $50,000, a salvage value of $10,000, and a useful life of five years and 3,000 units, as shown in the screenshot below.
