As we probably heard or read before, the F1-score is simply the harmonic mean of precision (PRE) and recall (REC) F1 = 2 * (PRE * REC) / (PRE + REC) What we are trying to achieve with the F1-score metric is to find an equal balance between precision and recall, which is extr...
Split the dataset into a separate training and test set. Train the model on the former, evaluate the model on the latter (by “evaluate” I mean calculating performance metrics such as the error, precision, recall, ROC auc, etc.) Scenario 2: Train a model and tune (optimize) its hyperp...
Sensitive to Outliers:The mean is sensitive to extreme values, also known as outliers. Outliers can significantly affect the mean value, leading to potentially misleading results. Mean Formula in Excel:In Excel, you can calculate the mean using the AVERAGE function. Simply input the range of data...
If there are even numbers of values, we calculate the mean of the values in the middle to find the median. Median = (4+6)/2 = 10/2 = 5 Mode The mode of a data set is the value appearing most often in the set. Mode formula Mode = Most occurring value Let’s consider the ...

The standard error is a measure of the precision of the sample mean as an estimate of the population mean. It accounts for both the variability within each group and the size of the sample. The smaller the standard error, the more reliable your estimate of the mean. To calculate the stand...
To calculate the TWR, you find the rate of return from each chapter and add one to it. Once you have gotten the rate of return for each chapter, multiply them together. Finally, subtract one from that total. By doing so, you are essentially weaving together the separate tales of ea...
How to Calculate the Dividend Growth Rate An investor can calculate the dividend growth rate by taking an average, or geometrically for more precision. As an example of the linear method, consider the following. A company's dividend payments to its shareholders over the last five years were: ...
To calculate it, you have to divide the number of conversions (when someone makes a purchase or completes an action) by the total number of clicks on your ad, and then multiply by 100. Andvoila,you have your PPC conversion rate.
