The max() function in Pandas Series is used to find the maximum value within a Series. It returns the highest value present in the Series. It returns a float value representing the maximum value within the series. This function always returns a Series even if only one value is present....
Now let’s go through the code step by step to understand the process of calculating max deviation in a Pandas DataFrame: 1. First, we import the pandas library and create a sample DataFrame with a single column named ‘Value’. 2. We then calculate the mean and median of the data usin...
