1. Scenario 1

   Worked example

   DatasetMath steps

   Scenario

   Using the sample Kifuliiru field values below, compute Phonological Entropy.

   Input data

   Illustrative inputs

   Quantity	Symbol	Value
   Entropy in bits (information density)	H	1
   Probability of phoneme x_i occurring	p(x_i)	0.63

   Reasoning

   Use the listed values (H = 1, p(x_i) = 0.63) in the formula, then complete the remaining symbolic step by hand or in the playground. Interpret the result against the formula's stated purpose.

   Computation

   $$H=-\sum p(x_i)\cdot {\log }_2(p(x_i))$$
