Working Scienctifically Flashcards
Close to the true value of what you are measuring.
Accurate
The process of looking at data and writing about what you have found out.
Analyse
A way of presenting data when one variable is discrete or categoric and the other is continuous.
Bar chart
A variable that has values that are words.
Categoric
What you write down to say what you have found out during an investigation.
Conclusion
How sure you are of your conclusion based on the data.
Confidence
A variable that has values that can be any number.
Continuous
A variable that you have to keep the same in an investigation.
Control variable
Words or numbers that you obtain when you make observations or measurements.
Data
A variable that changes when you change the independent variable.
Data
A variable that can only have whole-number values.
Discrete
To discuss the quality of data collected during an investigation and suggest improvements to the method.
Evaluate
A variable you change that changes the dependent variable.
Independent variable
An experiment or set of experiments designed to produce data to answer a scientific question or test a theory.
Investigation
A way of presenting results when there are two numerical variables.
Line graph
A smooth line on a graph that travels through or very close to as many of the points plotted as possible.
Line of best fit
An average of a set of data, found by adding together all the values in the set and dividing by the number of values in the set.
Mean
Carefully looking at an object or process.
Observation
A result that is very different from the other measurements in a data set.
Outlier
A way of presenting data when one variable is discrete or categoric and the other is continuous.
Pie chart
A description of how you will use equipment to collect valid data to answer a scientific question.
Plan
This describes a set of repeat measurements that are close together.
Precise
A statement that says what you think will happen.
Prediction
An error that causes there to be a random difference between a measurement and the true value each time you measure it.
Random error
The difference between the lowest and highest values a variable can have.
Range
When you repeat measurements in an investigation and get similar results they are repeatable.
Repeatable
When other people carry out an investigation and get similar results to the original investigation the results are reproducible.
Reproducible
A description of how you will make it less likely that people will be injured, or equipment damaged, and what to do if this happens.
Risk assessment
The difference between the highest and lowest measurements of a set of repeat measurements.
Spread
An error that causes there to be the same difference between a measurement and the true value each time you measure it.
Systematic error
The doubt in the result because of the way that a measurement is made.
Uncertainty
A quantity that can change, for example, time, temperature, length, mass.
