Statistical Analysis www.psychlotron.org.uk • Small relationships are detectable between any data sets • They may be caused by chance • They may be caused by something else • Statistical tests help us decide, for any given sets of data, which of these possibilities is more likely
Statistical Analysis www.psychlotron.org.uk • If we find that it is highly probable that the relationship was caused by chance, then we assume it was caused by chance • i.e. we accept the null hypothesis • If we find that it is highly improbable that the relationship was caused by chance, then we assume it was caused by something else • i.e. we reject the null hypothesis
