  • 1. Data Analysis S. Hallum Jordye Bacon Elementary School 5 th Grade
  • 2. Georgia Standards <ul><li>M5D1. Students will analyze graphs. </li></ul><ul><li>a. Analyze data presented in a graph. </li></ul><ul><li>b. Compare and contrast multiple graphic representations (circle graphs, line graphs, line plot graphs, pictographs, Venn diagrams, and bar graphs) for a single set of data and discuss the advantages/disadvantages of each. </li></ul><ul><li>c. Determine and justify the mean, range, mode, and median of a set of data. </li></ul>
  • 3. Terms <ul><li>Mean : The sum of the numbers in a set of data divided by the number of pieces of data. </li></ul><ul><li>Median : The number in the middle of a set of data when the data are arranged in order from least to greatest. When there are 2 middle numbers, the median is the number that is halfway between the two middle numbers. </li></ul>
  • 4. Terms <ul><li>Mode : The number that occurs most frequently in a set of numbers. </li></ul><ul><li>Range: The difference between the largest and smallest values in a numerical data set. </li></ul>
  • 5. Finding the Mean <ul><li>Step 1: Add all numbers in your set of data. </li></ul><ul><li>Step 2: Divide the sum by the number of pieces of data. </li></ul>Example: Set of Data: 15, 15, 14, 16 Sum: 60 Total number of pieces of data: 4 Mean: 60 ÷ 4 = 15
  • 6. Finding the Median <ul><li>Step 1: Put all numbers in order from least to greatest. </li></ul><ul><li>Step 2: Find the middle number. </li></ul>Example: Set of Data: 15, 15, 14, 16 Ordered: 14, 15, 15, 16 Middle Number: 15 and 15 Median: 15
  • 7. Finding the Mode <ul><li>Step 1: Put all numbers in order from least to greatest. </li></ul><ul><li>Step 2: Find the most popular number. </li></ul>Example: Set of Data: 15, 15, 14, 16 Ordered: 14, 15, 15, 16 Mode: 15
  • 8. Finding the Range <ul><li>Step 1: Put all numbers in order from least to greatest. </li></ul><ul><li>Step 2: Subtract the lowest number from the highest number. </li></ul>Example: Set of Data: 15, 15, 14, 16 Ordered: 14, 15, 15, 16 Range: 16 – 14 = 2

  • 10. Types of Graphs <ul><li>Bar Graph </li></ul><ul><li>Circle Graph </li></ul><ul><li>Line Graph </li></ul><ul><li>Line Plot Graph </li></ul><ul><li>Venn Diagram </li></ul><ul><li>Pictograph </li></ul>
  • 11. Bar Graph <ul><li>Definition: a graph that shows data using horizontal or vertical bars. </li></ul><ul><li>Advantages: </li></ul><ul><li>Easy to read </li></ul><ul><li>Compares multiple sets of data </li></ul><ul><li>Disadvantages </li></ul><ul><li>Not best for showing trends </li></ul>
  • 12. Circle Graph <ul><li>Definition: A graph that shows data in the form of a circle. </li></ul><ul><li>Advantages: </li></ul><ul><li>Shows percentages </li></ul><ul><li>Shows how a total is divided into parts </li></ul><ul><li>Disadvantages </li></ul><ul><li>Not best for showing trends </li></ul>
  • 13. Line Graph <ul><li>Definition: A graph that shows data in the form of a line. </li></ul><ul><li>Advantages: </li></ul><ul><li>Shows change over time </li></ul><ul><li>Helps you see trends </li></ul><ul><li>Disadvantages </li></ul><ul><li>Not easy to use to compare different categories of data </li></ul>
  • 14. Pictograph <ul><li>Definition: A graph that displays data using symbols or pictures. </li></ul><ul><li>Advantages: </li></ul><ul><li>Compares multiple sets of data </li></ul><ul><li>Visually appealing </li></ul><ul><li>Disadvantages </li></ul><ul><li>Hard to read when there are parts of pictures. </li></ul>
  • 15. Line Plot Graph <ul><li>Definition: A graph that uses symbols above a number line to display data. </li></ul><ul><li>Advantages: </li></ul><ul><li>An easy way to organize data </li></ul><ul><li>Disadvantages </li></ul><ul><li>Only good for one group of data and cannot be used to compare different categories of data or show trends. </li></ul>
  • 16. Venn Diagram <ul><li>Definition: Circles that show relationships among sets. </li></ul><ul><li>Advantages: </li></ul><ul><li>Shows comparisons and contrasts easily. </li></ul><ul><li>Disadvantages </li></ul><ul><li>Does not show trends </li></ul>
