Unit 1: Data Cycle (English)

Y-Axis

• The horizontal line on a graph.

• The up-and-down (vertical) line on a graph.

• The diagonal line on a graph.

• The line that represents the data points.

X-Axis

• The vertical line on a graph.

• The side-to-side (horizontal) line on a graph.

• The diagonal line that represents a trend.

• The line that indicates the maximum value on a graph.

Experiment

• Carrying out tests or trials to see how things work.

• A theoretical analysis of a concept.

• A method of collecting data without intervention.

• A process of making predictions based on observations.

Population

• The whole group of people or things you want to study.

• A small sample of individuals selected from a larger group.

• The average number of individuals in a specific area.

• A statistical measure of a specific characteristic.

Circle Graph

• A graph shaped like a circle, divided into slices, that shows parts of a whole.

• A linear graph that represents data points on a straight line.

• A bar graph that uses rectangular bars to show comparisons between categories.

• A scatter plot that displays values for typically two variables for a set of data.

Survey

• A method of collecting data by observing behavior.

• A process of analyzing statistical data.

• Asking people questions to find out what they think or do.

• A technique for predicting future trends.

Biased

• When information is fair and balanced.

• When information is unfair or one-sided.

• When information is based on facts and evidence.

• When information is presented in a neutral manner.

Bar Graph

• A graph that uses lines to show trends over time.

• A graph that uses bars to show and compare categories.

• A graph that displays data in a circular format.

• A graph that uses dots to represent values.

Representative Sample

• A smaller group that shows the same mix as the population.

• A group that is larger than the population.

• A group that only includes the most popular members of the population.

• A random selection of individuals without regard to their characteristics.

Stem-and-leaf Plot

• A method to display data in a table format.

• A way to organize numbers by splitting them into a “stem” (the first digit or digits) and a “leaf” (the last digit).

• A graphical representation of data using bars.

• A technique for calculating the mean of a data set.
