Most of us grasp information quickly and easily with a _______________. 2. _______________, _______________ and _______________ present numbers and other kinds of information in picture form. 3. One of the simplest ways to organize numbers is to put them all together in _______________ and _______________. When we do this, we make a _______________. 4. Each table shows groups of data that _______________ to one another. 5. A bar graph is a picture of _______________ 6. The _______________ gives you information about what is pictured in the graph. 7. The bars on a _______________ bar graph extend from side to side. 8. The bars on a _______________ bar graph extend up and down. 9. Bar graphs also help you make a variety of _______________. 10. Draw the symbol that shows that some of the scale of a graph has been left out. HOW TO READ ANY GRAPH 11. First, read the _______________ of the graph. 12. Second, read the _______________ and range of numbers (_______________) along the sides. 13. Third, determine what _______________ the graph uses. 14. Fourth, look for _______________, _______________ and _______________. 15. List the steps you should follow when drawing a bar graph. FIRST - SECOND - THIRD - FOURTH - 16. Choose your units so that your graph fits into the _______________ you have. 17. The horizontal axis should be labeled with units of _______________. HINTS FOR HELPING YOU SELECT A SCALE FOR BAR GRAPHS 18. Find the _______________ and _______________ values you need to show. 19. Imagine how near to each othe the ends of the bars will be if you start the scale of the axis at _______________ and continue up to the largest value. If they end up with nearly the same height, thenit may be better to start _______________ the smallest value, and show that some values are left _______________. 20. _______________ of 5, 10, 50, 100, 1000 and so on make it easier to estimate values from the graph. Try to pick an interval so that you will have only _______________ to _______________ lines to draw. 21. A bar graph is good for showing _______________ or _______________ facts about several things, or for showing one or two facts over _______________ time periods. When you want to show changes over _______________, a vertical bar graph works best, with the time periods labeled across the _______________. 22. Bar graphs work best when you have only _______________ to _______________ groups of information to compare. 23. A circle graph usually shows how a _______________ is made up of _______________ parts. 24. Some people refer to circle graphs as _______________ _______________. 25. The whole circle graph represents _______________, and each slice shows a part of 100%. 26. Together all the parts (slices) equal _______________%. 27. The circle graph does not show change over _______________. 28. A circle graph helps you compare parts of a whole to each _______________ and to the _______________. 29. A line graph shows values of data over a certain _______________, by displaying the data as _______________ on a graph that make up a _______________ or a _______________. 30. On a line graph the information is shown as little dots, these dots form a _______________. 31. Whenever you use the line to estimate values in between the plotted values (dots), you are _______________ between the data. 32. If a line graph is a straight line, you are able to extend the graph, relying on the trend shown by the graph. This is called _______________, or _______________, the graph. 33. Extrapolate the following line graph. 34. Line graphs - whether _______________ or _______________ - show trends in the plotted data. 35. T F A curved line graph can be interpolated. 36. T F A curved line graph can easily be extrapolated. 37. When more than one quantity is shown, on a line graph, there must be some way to tell which line corresponds to which quantity. This is done with a _______________. FOLLOW THESE STEPS TO DRAW A LINE GRAPH 38. First, decide what you are trying to _______________. Choose a title that describes your graph accurately. 39. Second, choose the general _______________ for the axes. It may be helpful to arrange your information in a _______________ first, to see clearly what you want to graph. 40. Third, figure out what _______________ you want for your graph. Draw your axes. Mark and label them with the units youve selected. 41. Fourth, by going over and up form the _______________, plot the points for your graph. 42. Fifth, begin at your first point and draw a _______________ through the remaining points that best represents the data youve shown. The line may be straight or curved, depending on the _______________ between the values you are graphing. DSET(H-l8 (4V6*8DSET(H -h8y8jzj6*8DSETR -\-d-`   -XUnit 4 reading guideDSETR@-L-T-P-   -H
