Bar Graphs and Line Graphs Lesson 7-4. Bar Graph A bar graph uses vertical or horizontal bars to display numerical information. Bar graphs can be used.

Histogram Whiteboard Activity Is the following a histogram?

Frequency Tables Histograms. Frequency-How often something happens. Frequency Table- A way to organize data in equal intervals. Histogram- Shows how frequently.

Objectives Create stem-and-leaf plots.

FREQUENCY TABLES, LINE PLOTS, & HISTOGRAMS. TERMS Frequency  number of times that something happens **The key here is that frequency is always about.

Frequency Table 2-1. Vocabulary  Data – Information  Frequency Table – lists the number of times each item occurs in a data set.

GOAL: DISPLAY DATA IN FREQUENCY DISTRIBUTIONS AND HISTOGRAMS Section 1-8: Frequency Distributions and Histograms.

Notes 5.2Histograms A frequency table groups large amounts of data into intervals. The frequency is the number of times an item occurs within an interval.

Represent sets of data using different visual displays.

Section 13.7 Stem and Leaf and Histograms Objective: Students will make stem and leaf plots and histograms and use these to answer data questions. Standard:

I CAN make a frequency table. I CAN make a line plot

Frequency and Histograms. Vocabulary:  Frequency: The number of data values in an interval.  Frequency Table: A table that groups a set of data values.

Section 12.2 Frequency Tables, Line Plots and Histograms Algebra Concepts Section 12.2 Frequency Tables, Line Plots and Histograms

Frequency table-lists each data item with the number of times it occurs

Line plot-displays x marks above each value on a number line.

Histogram-show the frequencies of data as a graph

Histograms Label axes Determine intervals (these can be different) Mark Intervals (must be evenly spaced)

Determine the intervals Find the range. Choose the number of bars you want Divide the range by this number

How many miles from school to your house? Collect data Decide on intervals Make a frequency table Make the graph
