Examples
By CEFR Level
- The graph shows the frequency distribution of test scores in our class.
- Analysing the frequency distribution of website visits by hour helped us plan server capacity.

Learning
Memory Aids
Mnemonic
Think of a 'frequency' radio station playing different songs ('values'). The 'distribution' is the playlist showing how often each song gets played.
Conceptual Metaphor
DATA IS A LANDSCAPE (the distribution shows the 'hills' and 'valleys' of where data points are concentrated).

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'частотное распределение' in non-technical contexts where it would sound overly jargonistic. In general contexts, 'распределение частот' or 'распределение данных' is more natural.
Common Mistakes
- Using 'frequency' alone to mean 'frequency distribution'.
- Confusing 'frequency distribution' with 'probability distribution' (the latter is theoretical).
- Treating it as a plural noun (e.g., 'The frequencies distributions are...').

Frequently Asked Questions
No. A frequency distribution is the tabular or conceptual summary of the data. A histogram is one specific type of graph used to visually represent that distribution.
No, it is exclusively a noun phrase. The related action would be 'to distribute' data into frequencies or 'to construct/plot a frequency distribution'.
A frequency distribution describes observed, empirical data. A probability distribution describes the expected likelihood of outcomes for a random variable, based on a theoretical model.
Its primary domain is STEM and social sciences. However, it can appear metaphorically in fields like linguistics (word frequency distributions) or business analytics.
