Study Notes

Part 1: Steps of the Scientific Method

The document asks for definitions and examples of steps in the scientific method. Information for this is missing.

Part 2: Experimental Design

A doctor noticed faster relief in patients taking higher doses of a new headache medication.
An experiment was designed to test this.
Three groups of patients were given different dosages: placebo, low dose, and high dose.
Patients recorded how long their headache took to subside.
Data was collected on the time it took for relief in each group.
Results were analyzed to determine a correlation between dosage and time to relief.

Part 3: Types of Data

A survey was mentioned to determine student preferences in school.
Questions about homework hours are quantitative.
Questions about favorite subjects, or feelings about lunch options are qualitative.
Questions about the number of students in a math class are quantitative.

Part 4: Characteristics of Life

Eating a meal involves the characteristic of life related to nutrition and survival.
Healing a cut on a finger illustrates the body's response to injury and demonstrates a characteristic of life.

Part 5: Graphing

Five components of a graph are missing from the document.
Data for caffeine in drinks (Coke, Mountain Dew, Chocolate Milk, Monster Energy) was provided.
A graph was to be drawn using this data.

Additional Information

A graph for Instagram follower count for two actors after a movie's release was also included. Data was provided.
A list of topics for study includes steps of the scientific method, identifying variables (independent, dependent, and control), experimental and control groups, controlled experiments, and formulating a hypothesis.
Other topics were listed (types of graphs, qualitative/quantitative data, characteristics of life, cell theory, biological organization, theory vs. law)
