Independent variable

Dependent
The one you measure
Control
The variable you keep the same
Hypothesis
Your prediction / statement of what you think will happen
Accurate
If it is close to the true value
How can you make your data more accurate?
Repeat
Calculate a mean
Remove anomalies
How can you make an experiment valid?
By only changing 1 variable
Controlling anything that could affect the dependent variable
Range
The difference between the smallest and largest value
Anomaly
A result that does not fit the trend
Mean
Add the values and divide by the number of values
Continuous
Data that can be any value
Can a line of best fit be a curve?
Yes
Positive correlation
When the data increases as the x axis increases
Negative correlation
When the data decreases as the x axis increases
No correlation
When there is no relationship between the data and the x axis
