I have seen classification metrics like f1-score, precision and recall being reported both as fractions and percentages. These measures are between
1 and represent ratios.
Can we report them as percentages or do we have to stick to fractions? For example:
When we have a precision of
0.5can we say "The classifier has a precision of 50%." ?
Does it all account also for f1-score? Can we say "The classifier has a f1-score of 50%? F1-score is not exactly a ratio, but the harmonic mean of two ratios.
