Day 17 Science: Test on Scientific Method;

When scientists follow the steps of an experiment procedure, they're doing it in order to:

• Test the hypothesis

• Determine the problem they need to solve

• Establish a control group

• Waste time

Data that are qualitative are always-

• described in words
• represented in numbers
• repeated for verification
• the most accurate type of data

A hypothesis is-

• a possible explanation of an observation that can be tested
• a proven statement
• a conclusive statement
• a definite answer to a possible problem

The variable that is measured in the experiment is-

• the dependent variable
• the independent variable
• the control variable
• the hypothetical variable

The main reason that diagrams, tables and graphs of data are used by scientists is to-

• organize data
• verify the conclusion
• test a hypothesis
• create an experiment

The summary at the end of an experiment that explains the results. 

• conclusion
• procedures
• materials
• responding variable
