DATA MASTERY BOOST Look at the numbers in the box on the right. Which number is equivalent to the values in the box? UNIT SURPRISE!: DATA, STATISTICS, and PROBABILITY How do we make sense of the world around us? I can decide the right times to use bar graphs, circle graphs, line graphs, and data tables I can determine the right time to use bar, pie, line, and scatter graphs. HOOK IN MINI LAB: DATA COLLECTION! 1.What is your birthday month? 2.What percentage of people in the classroom prefer chocolate ice cream? Strawberry? Vanilla? Cookies and Cream? Mint chocolate Chip? Mini Lab Data (continued) 3. At 7 AM how awake do you feel on a scale of 1-5 (1=least, 5=most)?_______ List a time when you feel least awake ______ 4. At 10 AM how awake do you feel on a scale of 1-5 (1=least, 5=most)? List a time when you feel most awake ______ 5. At 1 PM how awake do you feel on a scale of 1-5 (1=least, 5=most)? 6. At 4 PM how awake do you feel on a scale of 1-5 (1=least, 5=most)? BAR Chart/Graph Has bars Comparing frequencies or how much per category Comparing parts : parts or whole : whole BAR GRAPH AXES Category titles PIE/CIRCLE Chart/Graph Is a circle or cylinder with slices Slices are proportional to percents. Comparing parts : whole and parts : parts LINE Plot/Graph Has points connected by lines. ALWAYS shows change over time Y axis behavior depends on x axis SCATTER Plot/Graph Has dots for data points Helps explore other relationships between two sets of data. LINE GRAPH AXES CFU Identify the bar, pie, line, and scatter plot. When you have an answer with reasoning (use notes). FOR COMPARING BAR Categories Frequency PIE Categories Percentages CHANGE & RELATIONSHIP SCATTER PLOT Relationship between two sets of data LINE GRAPH Change over time B,P, S, or L graph to represent a set of data? Is it comparing categories? Is there a relationship, or change over time? CFU: Which pairs are true? A. Comparison Bar graph B. Percentages Pie Chart C. Changes over time Line graph D. Relationships between two data sets Line graph E.Relationships scatter plot HOOK IN MINI LAB: DATA COLLECTION! 1.What is your birthday month? 2.What percentage of people in the classroom prefer chocolate ice cream?
