How are mass and weight different?
Mass is the amount of matter in an object. Weight is the amount of gravity pulling on an object.
What tool is used to measure length?
Metric ruler
What unit is typically used to measure length?
Meters (kilometers, centimeters, and millimeters can work as well)
Amount of matter in an object
Median
Middle number in an ordered list of numbers
What is a bar graph used for? What is a line graph used for?
Bar graphs are used for comparisons. Line graphs are used to show a change over time.

Anomalous Data/Outlier
Doesn't fit with data set
How do you find density?
Mass divided by volume
What is numerical data? What is categorical data?
Numerical data is quantitative; shown in numbers (i.e. temperature, time, weight). Categorical data is qualitative; described using words or categories. (i.e. colors, food, sports).
