WebNormal distribution Approximate distribution of scores expected when a sample is taken from a large population. Drawn as a frequency polygon that often takes the shape of a bell-shaped curve, called a normal curve. Z scores In a normal distribution it tells you how far a number is above or below the mean in terms of standard deviations. WebNote: in the figures below, the Normal distribution is presented in red for comparison. In a skewed distribution, the scores tend to pile up toward one end of the scale and taper off gradually at the other end. The section where the scores taper off towards one end of a distribution is called the tail of the distribution. learn to write your name printable free
