To match the terms and definitions, we must understand the meanings of each term.
1. Statistics: the study of collecting, analyzing, interpreting, presenting, and organizing data.
2. Discrete variable: a variable that can only take specific, separate values. Examples include the number of children in a family or the number of cars sold in a month.
3. Continuous variable: a variable that can take any value within a range. Examples include temperature or height.
4. Population: the entire group or set of individuals or objects of interest to a researcher.
5. Qualitative data: data that consists of descriptive observations and characteristics. Examples include opinions, experiences, or colors.
6. Population parameters: numerical characteristics of a population that help describe or make inferences about the population.
7. Sample: a subset of the population selected for the purposes of a study.
8. Bias: a systematic error or deviation from the true value, caused by a flaw in the study design or data collection process.
9. Representative sample: a sample that accurately represents the characteristics of the population from which it was drawn.
10. Experimental study: a study in which the researcher actively manipulates variables to observe the effect on the participants.
11. Observational study: a study in which the researcher observes and measures variables without interfering or manipulating them.
12. Double-blind study: a study in which neither the participants nor the researchers know which participants are in the control or experimental group, helping to reduce bias.
13. Mean: the average of a set of numbers calculated by summing all the values and dividing it by the number of values.
14. Mode: the value or values that occur most frequently in a dataset.
15. Median: the middle value in a dataset when it is ordered from least to greatest.
16. Unimodal: a dataset that has one mode, meaning one value occurs most frequently.
17. Relative frequency: the proportion or percentage of times a specific value appears in a dataset.
18. Standard deviation: a measure of the spread or dispersion of data points around the mean.
