Scientific Method Review

Data that are qualitative are always-

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

What is NOT an example of qualitative data?

• the average high daily temperature for the month of july
• the names of chemicals found in breakfast cereal
• the zip codes in which each high school student resides
• types of shoes worn by pedestrians on a city street 

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

Which of the following must be done for the results of an experiment to be considered valid?

• the experiment must be repeated numerous times and the same results are obtained
• the results must be published in a national journal
• the results must be shown in a graph
• the results must be only quantitative

A hypothesis is a statement that-

• can be tested
• is almost always true
• is almost always false
• is the same as a theory

Should experiments be repeated over and over to see if the results are the same each time?

• yes
• no

There are two types of data. Which type of data involves descriptions that cannot be counted or measured?

• qualitative
• quantitative

This is the responding variable, or the variable you don't control.
