Key Aspects in an experiment

What is the definition if a hypothesis?

• The changing variable

• A formal explanation of what you will do

• A list of equipment you will need

• A prediction of what you think will happen

What is an experiment?

• A story

• A scientific test designed to investigate a hypothesis

• A mathematical equation

• A toaster

Why is it important to have control variables in an experiment?

• To increase the complexity of the experiment

• Because Wil said so

• To compare the results with an unaltered group

• To confuse the results

What is the purpose of a variable in an experiment?

• To measure changes in the experiment

• to clean the tables

• To make the experiment more complicated

• To make the experiment more interesting

What is the difference between a dependent and independent variable?

• There is no difference between dependent and independent variables.

• The dependent variable is the variable that is measured, while the independent variable is the variable that is manipulated.

• The independent variable is the variable that is measured, while the dependent variable is the variable that is manipulated.

• There is an "i" at the start

What is a conclusion?

• The summary of the results of an experiment

• A prediction of what will happen in an experiment

• A random thought about the experiment

• gathering ideas at the beginning of the experiment

What is the difference between accuracy and precision?

• There is no difference between accuracy and precision.

• The existential limitations of synonymous figuration.

• Accuracy is how close multiple measurements are to each other, while precision is how close a measurement is to the true value.

• Accuracy is how close a measurement is to the true value, while precision is how close multiple measurements are to each other.

Why is it important to repeat an experiment?

• To make the experiment more difficult

• to see if yours is better.

• To ensure that the results are consistent and not due to chance

• To increase the complexity of the experiment

What is a variable that remains constant throughout an experiment?

• Control variable

• Flat variable

• Dependant variable

• independent variable
