If 5% absence - deduct 2.5% and 10% absence - deduct 7%. How to get deduction percentage if the given absence rate is below 5%?

If the given absence rate is below 5%, you can use linear interpolation to estimate the deduction percentage.

Linear interpolation is a method used to estimate values that fall between two known values. In this case, we have two known values: 5% absence with a 2.5% deduction and 10% absence with a 7% deduction.

To perform linear interpolation, you need to calculate the difference between the two known absence rates and the corresponding deduction percentages. Then, you can use that difference to estimate the deduction percentage for absence rates below 5%.

Let's break it down:

1. Calculate the difference in absence rates:
Difference in absence rates = 10% - 5% = 5%

2. Calculate the difference in deduction percentages:
Difference in deduction percentages = 7% - 2.5% = 4.5%

3. Calculate the deduction percentage for absence rates below 5%:
Deduction percentage = 2.5% + (absence rate - 5%) * (difference in deduction percentages / difference in absence rates)

So, if the given absence rate is below 5%, you can use the formula above to estimate the deduction percentage. Just substitute the desired absence rate into the formula.

For example, if the absence rate is 3%:

Deduction percentage = 2.5% + (3% - 5%) * (4.5% / 5%) = 2.5% - 0.4% = 2.1%

Therefore, if the absence rate is below 5%, the deduction percentage can be estimated using linear interpolation.
