81. Graphing Skills: Histograms PART II: HISTOGRAM 1. Make a prediction about the remaining years of life that would be expected for someone in the current age category of 91-100.  Some students will attempt to find a mathematical trend in the data by looking at how the years change over each interval. Students should answer between 0 and 2 years if using this type of pattern. 2. Is the answer to question 1 an accurate number? Why or why not? Justify your answer.  No, the answer in 1 is not an accurate number. This is very difficult to predict from a graph of this type.

82. Graphing Skills: Histograms 3. What type of data is easily represented by a bar graph?  Data that compares amounts or frequency of occurrence. 4. What is the importance of scaling?  Scaling is important for making accurate comparisons.

84. Introduction to Line Graphs OBJECTIVE Students will become familiar with the basic skills used in making line graphs. Line graphs will be used throughout their science course of study.

85. Introduction to Line Graphs Graphs are useful tools in science because trends in data are easy to visualize when represented graphically. Line graphs can be used to show how something changes over time or the relationship between two quantities. They can also be readily used to interpolate (predict between measured points on the graph) and extrapolate (predict beyond the measured points along the same slope) data points that were not actually measured.

86. Line Graphs PURPOSE In this activity you will learn the basic procedure for constructing and analyzing line graphs. MATERIALS graph paper Data pencil ruler

87. Line Graphs Following the steps below will help ensure that all components of the graph are correctly displayed. 1. Identify the variables. Independent on the x-axis and dependent on the y-axis 2. Determine the range. For each axis subtract the lowest value data point from the highest value data point. 3. Select the scale units. Divide each axis uniformly into appropriate units using the maximum amount of space available. (Remember that the axes may be divided differently but each square along the same axis must represent the same interval.) 4. Number and label each axis. Be sure to include units where appropriate as part of the axis label.

88. Constructing a Line Graph Steps 5. Plot the data points as ordered pairs. (x,y) 6. Draw the best straight line or best smooth curve. For a straight line, use a straight edge to draw your line in such a way that equal numbers of points lie above and below the line. 7. Title the graph. The title should clearly describe the information contained in the graph. It is common to mention the dependent variable (y-axis) first followed by the independent variable (x-axis).

89. Line Graph Data Construct a line graph using the following data about hatching time and temperature. Make sure to follow the steps on your line graph sheet. Remember TALKS!
