Study Notes

Graphs and Data Representation

Bar Graph: Utilizes horizontal or vertical bars to display countable data for easy comparison.
Dot Plot: Visualizes frequency of data points along a number line, representing individual values with dots.
Histogram: Specialized bar graph that represents the frequency of data within specified intervals.
Line Graph: Illustrates how data changes over time using connected line segments, useful for tracking trends.

Data Concepts

Data: Collected information about people or things, typically analyzed to derive insights or conclusions.
Frequency: The count of occurrences of a specific event or value within a data set.
Frequency Table: Organized table that records how often each event occurs, providing a clear view of data trends.

Measures of Central Tendency

Mean: Calculated by summing all data items and dividing by the amount of items; represents the average.
Median: Middle value of an ordered data set, or average of the two middle values if the set contains an even number of items.
Mode: Reflects the most frequently occurring value(s) within a data set, indicating common occurrences.

Data Distribution

Outlier: Anomalous value significantly higher or lower than other values in a data set, which can skew results.
Relative Frequency Table: Displays the percentage occurrence of each data value, highlighting the distribution with context.

Statistical Inquiry

Statistical Question: Queries that concern datasets with varying values, requiring analysis or exploration of data trends and patterns.
