Difference between a Pandas Series and a DataFrameBoth DataFrame and series are the two main data structure of pandas library. Series in pandas contains a single list which can store heterogeneous type of data, because of this, series is also considered as a 1-dimensional data structure. On...

Standard Deviation vs. Standard Error If you need to draw conclusions about the spread and variability of the data, use standard deviation. If you’re interested in finding how precise the sample mean is or you’re testing the differences between two means, then standard error is your metric....
