Here's a breakdown:
* "Un" means not.
* "Representative" refers to something that accurately reflects the characteristics of a larger group.
Here are some examples of how "unrepresentative" might be used:
* "The survey results were unrepresentative because they only included people from one particular city." This means the survey didn't capture the views of the wider population.
* "The movie's cast is unrepresentative of the real-world diversity of the city." This means the movie doesn't show a realistic representation of the city's inhabitants.
* "The government's decision was made by an unrepresentative group of politicians." This implies that the decision was made by a small group of people whose views don't reflect the majority of the population.
Essentially, "unrepresentative" describes something that doesn't provide a fair or accurate portrayal of the whole.
