  14. The purpose of a bar graph is to display and compare data. Bar graphs use bars to show the data. A bar graph must include: - a title - labeled X and Y axes - equal intervals are used on the Y axis - the bars are evenly spaced apart from each other Return to Graph Bar Graph

  15. Return to Graph Stem and Leaf Plot • Stem and leaf plots are used as a quick way of seeing how many pieces of data fall in various ranges. The reader can quickly tell: - the range - the mode • Stem and leaf plots have a title, a stem, and leaves • A key is used to explain how to read the stem and leaves.

  16. All pictographs have a title. Rows and columns shape the pictograph. Label each row and column. Use pictures to show the data. Each picture equals a certain amount of data. Pictographs need a key. Return to Graph Pictograph

  17. A line graph is used to illustrate change over time. Line graphs need: - Title - Labeled X and Y axes - Equal Intervals - Data displayed by points connected into lines Return to Graph Line Graph

  18. A double line graph is used to compare two groups of related data over time. Double line graphs need: - Title - Labeled X and Y axes - Equal Intervals - Data displayed by points connected into lines - Key Return to Graph Double Line Graph

  19. Circle graphs are used to display parts of the data in relation to the entire amount of data. All circle graphs need a title. Each part is called a sector and is labeled. All angles correct (+2/-2 degrees) Return to Graph Circle Graph

  20. The purpose of a double bar graph is to compare two or more sets of data. Uses bars to show the data. Double bar graphs must include: - Title - Labeled X and Y axes - Equal intervals are used on the Y axis - Pairs of bars are equally spaced, but the compared bars are not - Key Return to Graph Double Bar Graph

  21. Return to Graph Line Plot • A line plot shows the spread of all the data on a number line. • Easily identifies the mode. • All line plots include: - a title - a numbered horizontal line - data displayed by use of X’s

  22. Histograms are used to show the frequency of data. Very similar to bar graphs, but use intervals on the X axis. Bars do touch. Histograms have a title. Histograms have two axes which are labeled. Return to Graph Histogram

  23. Displays large set of data. Gives general idea of how data clusters. Graph includes: - Title - Labeled intervals - Box between lower and upper quartiles - Whiskers from quartiles to extremes - Median, quartiles and whiskers labeled Return to Graph Box - and - Whisker Plot

  24. Shows how closely two sets of data are related The closer the sets are related, the closer the points come to forming a straight line. Scatter Plots include: - title - labeled axes - equal intervals - corresponding numbers plotted as ordered pairs Return to Graph Scatter Plot
