  • Correlation

    Correlation refers to a connection—direct relationship, inverse relationship, or otherwise—between data.

  • Negative correlation

    If two variables trend in opposite directions (one increases as the other decreases) there is a negative correlation.

  • Positive correlation

    If two variables trend together, that is as one increases so does the other, there is a positive correlation.

  • Correlation coefficient

    Relationships can be quantified with a correlation coefficient, a number between –1 and +1 that represents the strength of the relationship. A correlation coefficient of +1 indicates a strong positive relationship, a value of –1 indicates a strong negative relationship, and a value of zero indicates no apparent relationship. 

  • Correlation does not necessarily _____.

    imply causation

  • The only one of Hill’s criteria that is uniformly necessary for causation is _____.
