The questions that could be answered by collecting data that has variability are:
- What proportion of the voters want a new city park?
- How many people own snow blowers in Boston?
- On average, how old are the cats that live in Kyle's neighborhood?
What is variability?
Variability refers to the extent to which data points in a dataset differ or spread out from the average or central tendency. It measures the degree of diversity or dispersion among a set of values.
Variability is crucial in statistics as it helps in understanding the distribution of data, identifying patterns, making predictions, and drawing conclusions about the data.
