Data Analysis and Measurement Quiz

Study Notes

Terms and Definitions

Labeling: The process of attaching numbers or labels to objects or events for identification or analysis.

Understanding Data

Data: Information collected for analysis, often in numerical form, used to represent facts, concepts, or measurements.

Measures of Central Tendency

Mean: The average value calculated by summing all numbers and dividing by the count of values.
Median: The middle value in a dataset when arranged in ascending or descending order; if an even number of values, the median is the average of the two middle numbers.
Mode: The value that appears most frequently in a dataset; may be more than one mode if multiple values have the highest frequency.

Measures of Variability

Range: The difference between the highest and lowest values in a dataset, indicating the spread.
Variance: A measure of how much the values in a dataset vary from the mean, showing the average of the squared differences from the mean.
Standard Deviation: The square root of variance, providing a measure of data dispersion around the mean; a low standard deviation indicates that values tend to be close to the mean.

Outcomes of Data Analysis

Insights: Enhanced understanding of the data, identifying trends, patterns, and anomalies that aid decision-making.
Predictions: Forecasting future trends based on historical data patterns.
Decision Support: Providing evidence to inform business, scientific, or policy decisions effectively.
