Correlations

• Correlation

  A mathematical technique in which a researcher investigates an association between 2 co-variables.
• Co-variables

  Variables investigated within a correlation e.g height and weight.
• Positive correlation

  As one co-variable increases so does the other.

  E.g Number of people in a room and noise.
• Negative correlation

  As one co-variable increases the other decreases.

  E.g number of people in a room and amount of personal space.
• Zero correlation

  When there is no relationship between co-variables.

  E.g number of people in a room in Manchester and total daily rainfall in Peru.
