A histogram is a type of bar graph that represents the distribution of data. It is used to show the frequency of values within a data set. In a histogram, the horizontal axis represents the range of values, and the vertical axis represents the frequency or relative frequency of those values.
Key Concepts
Frequency: The number of times a particular value occurs in the data set.
Range: The span of values covered by the data set.
Bar Height: The height of each bar in the histogram represents the frequency or relative frequency of the corresponding value.
Intervals: The range of values is divided into intervals or bins, and each bar represents the frequency of values within that interval.
Knowledge of Measurement: Students will identify attributes, units, or systems of measurements or apply a variety of techniques, formulas, tools, or technology for determining measurements.
Applications in Measurement: Calculate equivalent measurements.
Determine start, elapsed, and end time (Assessment limit: Use the nearest minute).
