Data: information about the characteristics of a group of individuals. Categorical variable: describes a particular characteristic which can be divided into categories. Quantitative variable: describes a characteristic which has a numerical value that can be counted or measured. Population: an entire collection of individuals about which we want to draw conclusions. Bias: is a term used to describe statistics that don't provide an accurate representation of the population. Census: the collection of information from the whole population. Parameter: a numerical quantity measuring some aspect of a population. Sample: a group of individuals selected from a population. Survey: the collection of information from a sample. Statistic: a quantity calculated from data gathered from a sample, usually used to estimate a population parameter.
Understand the Problem
The question provides definitions and descriptions of various statistical terms related to data collection and analysis. It outlines key concepts such as data, variables, population, bias, census, parameter, sample, survey, and statistic, helping to clarify how these terms are interrelated and used in statistics.
Answer
Categorical variables describe characteristics in groups; quantitative variables have numerical values.
Categorical variables are used to describe characteristics that can be put into groups, such as gender or race, while quantitative variables describe characteristics that have numerical values, such as age or height.
Answer for screen readers
Categorical variables are used to describe characteristics that can be put into groups, such as gender or race, while quantitative variables describe characteristics that have numerical values, such as age or height.
More Information
Quantitative variables can further be divided into discrete and continuous types. Discrete variables represent counts (e.g., number of siblings), while continuous variables represent measurements (e.g., height).
Tips
A common mistake is confusing categories (qualitative) with numeric values (quantitative). Ensure you distinguish groupings from measurements.
