Data Analysis and Experimental Design

Mr. Andersen discusses AP Biology science practice 5, focusing on analyzing data and evaluating evidence. He emphasizes the importance of organizing data, identifying patterns, and controlling for variables. The video covers examples like Charles Keeling's CO2 data, fertilizer effects on plant growth, and various biological contexts. It also highlights the need to identify errors and visualize data effectively, using examples from genetics and NASA's data visualization efforts.

What is the primary focus of Charles David Keeling's data collection?

• Plant growth

• Atmospheric carbon dioxide

• Genetic inheritance

• Ocean currents

Why is it important to organize data into graphs?

• To avoid data collection errors

• To reduce the amount of data

• To make it look more complex

• To identify patterns and relationships

What is the significance of identifying patterns in data analysis?

• To simplify data collection

• To predict future trends

What is a potential source of error in the potato lab data set?

• Inconsistent sucrose solutions

• Mislabeled beakers

• Incorrect initial mass measurement

• Inaccurate temperature control

In a predator-prey relationship, what happens when prey numbers increase?

• Prey numbers decrease

• Prey numbers stabilize

• Predator numbers increase

• Predator numbers decrease

What is the purpose of refining a data collection protocol?

• To ensure data validity

• To reduce data volume

• To simplify data analysis

• To increase data complexity

What genetic phenomenon is described by one gene affecting the expression of another?

• Linkage
