We can use the built-in function called “MEDIAN” to calculate the median in Excel. The syntax for the MEDIAN function is as follows: We can use the MEDIAN function in two ways: 1. Range of Dataset Here, we must add the cell range for the data in the function as the first argument...
In the long run, cracks need to be repaired. However, our resources are limited, so we need to decide which cracks are more dangerous. To make this decision, we need to be able to predict how different cracks will grow. There are several empirical formulas describing crack growth. In ...
Calculating a bacterial culture’s Growth Rate requires experimental data, and the formula must be compatible with the bacteria’s characteristics. We calculate the Bacterial Growth Rate using a typical empirical formula. Use yours that is compatible with the bacteria’s characteristics. ...
