Experimental Design Flashcard

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is an experiment?

Back

An experiment is a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.

Front

What is the purpose of a control in an experiment?

Back

A control is used as a standard of comparison to ensure that the results of an experiment are due to the independent variable.

Front

What does it mean to plot a graph?

Back

Plotting a graph means to represent data visually using points, lines, or bars to show relationships between variables.

Front

What is the X-axis in a graph?

Back

The X-axis is the horizontal line on a graph that typically represents the independent variable.

Front

What is the Y-axis in a graph?

Back

The Y-axis is the vertical line on a graph that typically represents the dependent variable.

Front

What is a hypothesis?

Back

A hypothesis is a proposed explanation for a phenomenon, which can be tested through experimentation.

Front

What is the significance of measuring sprint times in a speed experiment?

Back

Measuring sprint times provides quantitative data to evaluate the effect of training conditions on sprinter performance.

Front

How does varying sunlight exposure affect plant growth?

Back

Varying sunlight exposure serves as an independent variable that can influence the growth rate of plants, which is the dependent variable.
