Probability and Statistics
Focus: Practical Applications of Statistics

The student, given a problem situation, will
a)   construct circle graphs;
b)   draw conclusions and make predictions, using circle graphs; and
c)   compare and contrast graphs that present information from the same data set. 
Essential Knowledge and Skills
  • Collect, organize and display data in circle graphs by depicting information as fractional.
  • Draw conclusions and make predictions about data presented in a circle graph.
  • Compare and contrast data presented in a circle graph with the same data represented in other graphical forms.
Essential Understandings
  • What types of data are best presented in a circle graph? Circle graphs are best used for data showing a relationship of the parts to the whole.

  1. Box-and-Whisker Plots: Construct a box‑and‑whisker plot to match a line plots, and construct a line plot to match a box‑and‑whisker plots. Manipulate the line plot and examine how the box‑and‑whisker plot changes. Then manipulate the box‑and‑whisker plot and examine how the line plot changes.
  2. Describing Data Using Statistics: Investigate the mean, median, mode, and range of a data set through its graph. Manipulate the data and watch how the mean, median, mode, and range change (or, in some cases, how they don't change).
  3. Graphing Skills: Create a graph (bar graph, line graph, pie chart, or scatter plot) based on a given data set. Title the graph, label the axes, and choose a scale. Adjust the graph to fit the data, and then check your accuracy. The Gizmo can also be used to create a data table based on a given graph.
  4. Histograms: Change the values in a data set and examine how the dynamic histogram changes in response. Adjust the interval size of the histogram and see how the shape of the histogram is affected.
  5. Line Plots: Build a data set using a line plot. Find its mean, median, mode, and range. Change the data values by dragging the points, and watch how the mean, median, mode, and range change (or, in some cases, do not change).
  6. Mascot Election (Pictographs and Bar Graphs): A brand new school is opening and it is time to elect the school mascot! Students can choose the Eagle, Lion, Bear, or Wolf. Voting results can be displayed in a table, tally chart, pictograph, bar graph, circle graph, or dot plot. You can change student votes by selecting a group of students and clicking a mascot.
  7. Scatter Plots - Activity A: Examine the scatter plot for a random data set with negative or positive correlation. Vary the correlation and explore how correlation is reflected in the scatter plot and the trend line.
  8. Stem-and-Leaf Plots: Build a data set and compare the line plot of the data set to the stem‑and‑leaf plot.
  9. Reaction Time 2 (Graphs and Statistics): Test your reaction time by catching a falling ruler or clicking a target. Create a data set of experiment results, and calculate the range, mode, median, and mean of your data. Data can be displayed on a list, table, bar graph or dot plot. The Reaction Time 2 Student Exploration focuses on mean.
  10. Populations and Samples: Compare sample distributions drawn from population distributions. Predict characteristics of a population distribution based on a sample distribution and examine how well a small sample represents a given population.

VDOE Interventions
  1. VDOE Algebra Readiness Curriculum Companion: Exploring Statistics - The lessons focus on methods of data collection and use of technology to represent data with various types of graphs. Students learn that different graphs represent different types of data effectively and to use measures of center and dispersion to analyze and interpret data. (pdf)
