Compare percentages only after checking the denominators
Scientific comparisons can be misleading when two groups have different sizes. Work with the denominator before deciding which result is larger.
A practical example
In a fictional dataset, 12 of 40 seeds germinate in one condition and 18 of 90 in another. The percentages are 30% and 20%. The second group has more germinated seeds in total, but a smaller proportion. Both statements can be true.
Write the conclusion with the quantity named: number germinated or percentage germinated. Then discuss what further information would be needed to judge the investigation, including how the groups were selected. Online tuition can review this reasoning; do not assume a separate Walsall teaching location.
Distinguish a trend from a causal claim
A fictional survey finds that pupils who spend more time outdoors also report more exercise. The association alone does not show which factor causes the other or rule out a third explanation.
Ask what was measured, how the sample was selected and which variables were not controlled. Write one cautious conclusion supported by the survey and one claim that goes beyond it. This strengthens data interpretation without requiring a new experiment or pretending that a larger correlation automatically becomes proof of causation.
Before you arrange support
Where are in-person lessons based?
Teaching Success’s in-person base is Smethwick. This guide is for online enquiries from families elsewhere, with the tutor, subject and times confirmed before booking.
What should I include in an enquiry?
Include the subject, year group, exam board or tier where relevant, and the learning goal. Kevin and Serena will confirm whether suitable support and times are available.
