Question

graphing skill #1: what type of graph is it? there are several types of graphs that scientists often use to display data. they include: pie graphs, bar graphs, histograms, line graphs, scatter plots. based on these definitions, and the descriptions of the experiments below, please put an \x\ in the box for the type of graph that would be most appropriate (some descriptions may have several graph types that would be appropriate; you only need to select one). description pie bar histo. line scatter a graph showing the number of 5th - graders who prefer coke or pepsi. a graph showing how a newborn babys weight changes over time. a graph showing the percentage of the class earning as, bs and cs. a graph showing the distribution of trees of different sizes (e.g. 0 - 10 m, 10 - 20cm, etc.) in a forest. a graph showing the relationship between height and arm - length. a graph showing the percentage of an allowance spent on different categories (e.g. food, movies, etc.). a graph showing the amount of rainfall, by month. a graph showing the number of ice - cream cones sold at different times of the days temperature. a graph showing whether a plants flower color has a which - breeding pattern.

Explanation:

1. For "A graph showing how a newborn baby's weight changes over time", a line - graph is appropriate as it shows changes over a continuous variable (time).
2. For "A graph showing the percentage of the class earning As, Bs and Cs", a pie - graph is suitable as it shows proportions of a whole.
3. For "A graph showing the distribution of trees of different size groups (e.g. 0 - 10 cm, 10 - 20 cm etc.) in a forest", a histogram is appropriate as it represents the distribution of a continuous variable grouped into intervals.
4. For "A graph showing the relationship between height and weight", a scatter - plot is best as it shows the relationship between two continuous variables.
5. For "A graph showing the percentage of an allowance spent on different categories (e.g. food, movies, etc.)", a pie - graph is fitting as it shows parts of a whole.
6. For "A graph showing the amount of rainfall, by month", a line - graph is good as it shows changes over time (months).
7. For "A graph showing the number of ice - cream cones sold at different times of the day", a bar - graph can be used to compare the quantities at different time intervals.
