1

What is a correlation?

  • One thing causes another
  • Two things that tend to change together in a predictable way
  • A type of graph
  • A random coincidence
2

Does ice cream cause sunburns?

  • Yes — the data shows they are correlated
  • No — hot sunny weather (a third variable) causes both
  • Only in summer
  • We cannot know
3

What is a confounding variable?

  • An extra variable that is confusing
  • A hidden factor that causes both measured things to change, creating a fake connection
  • A variable in a science experiment
  • The average of two variables
4

What does 'correlation is not causation' mean?

  • Correlations are useless
  • Just because two things happen together does not prove one causes the other
  • Causation is better than correlation
  • You should ignore all correlations
5

How do scientists test if something really causes something else?

  • They look at correlations
  • They run controlled experiments with treatment and control groups
  • They ask people what they think
  • They cannot test causation
6

Students with bigger feet score higher on reading tests. Why?

  • Big feet help you read
  • Older students have bigger feet AND better reading skills — age is the confounding variable
  • It is a coincidence
  • Shoes help with concentration
7

What is a spurious correlation?

  • A very strong correlation
  • A correlation that is pure coincidence with no real connection
  • A correlation between two causes
  • A negative correlation
8

Is correlation useful even though it does not prove causation?

  • No — it is worthless
  • Yes — it helps spot patterns and generate questions for further testing
  • Only in science
  • Only when the correlation is strong
