Presentation on theme: "Data Display: Tables and Graphs"— Presentation transcript:
1Data Display: Tables and Graphs Communicating - Conveying oral or written information verbally as well as visually through models, tables, charts, and graphs.Predicting - Proposing possible results or outcomes of future events based on observations and inferences drawn from previous events.Applying process skills to interpret data from graphs, tables, and charts.
2Homework Assignment:Poll 25 of your friends to find out their favorite color (blue, green, red, pink, yellow, purple, or orange).
3TablesTables display data in columns and rows to make it easier to read and understand.
4GraphsThree types:- Line graph- Bar graph- Circle graph
6Line Graph Shows the relationship between two variables. What is a “variable”?Both variables in a line graph must be numbers.One variable is shown on the horizontal axis, or x-axis, of the graph.The other variable is placed along the vertical axis, or y-axis.
8Bar GraphA bar graph uses rectangular blocks, or bars, of varying sizes to show the relationships among variables.One variable is divided into parts.The second variable must be a number.The bars show the size of the second variable.
9Circle GraphA circle graph (“pie graph”) shows the parts of a whole.
10Some IMPORTANT Characteristics of Tables and/or Graphs: A titleLabeled columns and rows, or axesEvenly spaced scalesSome graphs have keys and/or color-coding. (See the circle graph.)
11Check Your Understanding! Suppose you have two variables, for example, how much salt you eat in a day and how much water you drink, and you want to visually depict their relationship across time. What visual tool might you use to show this relationship?When you put numerical data into rows and columns, you are creating a _______.
12Check Your Understanding! 3. Suppose you want to visually demonstrate how much of a given area is woodland, how much is grassy but has no trees, and how much has been developed. With different segments like this to consider, how might you choose to show the relationship of parts to the whole?
