Prediction
What you think will happen in an experiment,
1 of 26
Valid
The results and conclusions would be this if all the variables are correctly controlled,
2 of 26
Fair Test
This is where only the independant variable is changed and the other variables are controlled,
3 of 26
Hypothesis
A scientific statement that explains certain facts and observations,
4 of 26
Interval
This is the diffence between the values of the independant variable,
5 of 26
Data
Information you collect from an experiment,
6 of 26
Datum
One piece of information
7 of 26
Systematic Error
An error that repeats itself in every experiement- usually to do with the method,
8 of 26
Resolution
The smallest measurement on a piece of equipment,
9 of 26
Repeatable
If the same person can get the same results when repeating the experiment,
10 of 26
Categoric Variable
A variable that can be described with a label or category,
11 of 26
Control Variable
Variables that remain constant and are controlled,
12 of 26
Independant Variable
The variable that you are changing to causes a change in another thing
13 of 26
Continuous Variable
A variable that can have any numerical variable
14 of 26
Dependant Variable
The variable that is changed as a result of the change of the independant variable,
15 of 26
Uncertainty
The spread of results around the true value,
16 of 26
Measurement Error
The difference between the real value and the measured value,
17 of 26
Anomaly
A result thay does not fit the pattern,
18 of 26
Random Error
This error causes measurements to be spread around the true value so should not be included in the mean,
19 of 26
Zero Error
When a piece of equipment should be reading zero, but doesnt,
20 of 26
Accuracy
How close the reading is to the true value
21 of 26
Precision
Determined by the resolution of the equipement - mm is more recise then mm
22 of 26
Calibration
When we make sure the apparutus is reading the correct value
23 of 26
True Value
The real value of an experiement
24 of 26
Reproducible
If another person can get the same result, it means your experiment is reproducible,
25 of 26
Range
The maximum and minimum values for the independant and dependant variables.
