Key Takeaways

  • โ€ข Relative frequency: rf_i = f_i / n โ€” proportion of data in each category; sums to 1
  • โ€ข Percentage frequency: pf_i = rf_i ร— 100% โ€” easier to interpret; sums to 100%
  • โ€ข Cumulative relative frequency: crf_i = cf_i / n โ€” proportion at or below category i

Frequently Asked Questions

What is the difference between frequency and relative frequency?

Frequency is the raw count. Relative frequency = count/total, so it is a proportion between 0 and 1.

When should I use raw data vs frequency table?

Use raw data when you have individual observations. Use frequency table when data is already summarized.

What is cumulative relative frequency used for?

It shows the proportion of data at or below each category. Useful for percentiles and the ogive curve.

Disclaimer: Relative frequency assumes each observation is counted once. For weighted data, additional adjustments may be needed.
