We recommend using histograms to make it easier in perceiving, analyzing the results and presenting them to other users. The mathematical equation for normalization is as follows: $$\frac{raw~frequency}{N} \times 1,000,000 = freqeuncy~per ~million$$ where N is the number of tokens in the corpus. Cumulative Frequency Graph, Plot the cumulative frequency curve. For example, if the last frequency is in cell B12, enter “=B2/SUM(B$2:B$12)” in cell C2 to calculate the relative frequency of the value in A2. Iris-virginica 50 Iris-setosa 49 Iris-versicolor 45 versicolor 5 Iris-setossa 1 Name: class, dtype: int64 Notice that the value_counts() function automatically provides the classes in decending order. Find the median values. Depending on the type of data being analyzed, a data set may or may not include multiple instances of the same value. Use the fill down feature to extend the formula from C2 down to construct the relative frequency distribution. Relative frequencies are used to construct histograms whose heights can be interpreted as probabilities. The calculator will also spit out a number of other descriptors of your data - mean, median, skewness, and so on. Calculating Relative Frequency and side by side Bar Plots w/ Statcrunch ...
