    8. Shapes of Distributions Frequency distributions: represent the number of scores that occur at certain values of a variable. Distributions can take on a number of shapes or forms.

    9. Unimodal Distributions The mode: most frequently occurring score. A unimodal distribution has one mode.

    10. Multimodal Distributions Multimodal distributions: more than one mode. Bimodal distribution: two modes.

    11. Rectangular or Uniform Distributions Uniform distribution: all values are observed equally often

    12. Symmetrical Distributions A symmetrical distribution: if cut in half, the two sides would be mirror images of one another Normal Distribution: a particular kind of distribution that resembles a bell (bell-shaped curve)

    13. Skewed Distributions A skewed distribution is not symmetrical. It is unbalanced.

    14. Skew

    15. Negatively Skewed Distribution

    16. Positively Skewed Distribution
