Study Notes
Blood Type Differences in Populations
- A double bar graph enables simultaneous comparison of two sets of data across populations.
- Populations analyzed include Europeans, Americans, and Dunkers.
- Categories on the vertical axis represent blood types: A, B, Rh, M, MN, N.
Average Tuition at CSUF and UCI
- The grouped bar graph compares tuition costs at California State University, Fullerton (CSUF), and the University of California, Irvine (UCI).
- Observations can be made regarding the changes in tuition over time.
Horizontal Bar Graphs
- Horizontal bar graphs can display data such as fruit sales over specified dates.
- In the example provided, sales of apples, oranges, mangoes, star fruit, and papaya over two days are presented in kilograms.
Scatter Plots
- Scatter plots are used to explore relationships between two dependent variables.
- Each variable is assigned its own axis; a "best fit curve" indicates the relationship between them.
- A strong linear relationship appears when the curve closely fits the data points.
Shaquille O’Neal’s Growth Data
- Historical data of Shaquille O'Neal’s height, weight, and shoe size from age 4 to 25 can be utilized to create graphs.
- Significant milestones include reaching 7'1" and 310 pounds by age 25.
Spending on "Back to College"
- In 2007, US families spent $47.3 billion on back-to-college purchases, averaging $956.93 per student.
- Key expenditure categories may include textbooks, housing, and shoes.
Pie Charts
- Pie charts represent data as a percentage of a whole, illustrating composition rather than comparisons.
- Useful for visualizing the distribution of ingredients in a dish, such as the composition of a pizza.
Graph Labels and Legends
- Each graph must include axis labels and legends for clarity and to explain the data visually.
- Important terms related to data graphs: dependent, independent, line, linear, scatterplot, title, percentage.
Data Analysis Terms
- Mean, median, and mode are key statistical measures for data analysis.
- Understanding graph terminology and functions is essential for both creating and interpreting graphs in data representation.
