Hypothesis ✔✔A precise testable statement predicting the outcome of an experiment including
the relationship between the IV and t

he DV.
Independent Variable ✔✔Variable you later which produces the experiment conditions.
Dependant Variable ✔✔The variable you measure to see the effect of the IV.
Lab Experiment ✔✔Experiment with controlled conditions, lots of equipment.
Field Experiment ✔✔Experiment carried out in real life settings.
Natural Experiment/Qiasi ✔✔Experiment where you don't manipulate the IV, it naturally occurs.
Anomalous Result ✔✔Odd one out in data, result that does not match the rest of your results.
Quantitative Data ✔✔Any number data that can be interpreted objectively eg. numbers, dates,
birthdays.
Qualitative Data ✔✔Words, opinions or subjective data that cannot be interpreted objectively.
Mean ✔✔Average where you add all the numbers up together and divide by the number of
numbers eg. 3+3+2+3+4 divided by 5 = 3
Mode ✔✔The most popular number eg. 1,2,2,3,4 mode is 2
Median ✔✔The middle number when the numbers are in order from smallest to largest. In a

10/60x100=16.6%

your participant sample to match the correct percentage for each subgroup.
Systematic Sampling ✔✔Sampling method where every nth member of the target population is
selected eg. 7n would mean every 7th person is selected.
Opportunity Sampling ✔✔Sampling method where researchers choose only available and
willing participants.
Random Sampling ✔✔Sampling method where every member of the target population has an
equal chance of being selected as a participant. The names are often drawn out by computer
