distributions Flashcards
normal distribution
Most people fall somewhere in the middle of the possible scores.
Bell-shaped curve, symmetrical, the mean median and mode all fall on the same central point (highest peak), two tails never touch the horizontal axis.
negative skewed distribution
Left skewed, most get high scores and few get low scores - most of the scores are bunched towards the right. The mode is to the right of the mean because the mean is affected by the extreme scores tailing off to the left.
MODE = LARGEST
positive skewed distribution
Right skewed, most get low scores and few get high scores - most of the scores are bunched towards the left. The mode is to the left of the mean, because the mean is affected by the extreme scores tailing off to the right.
MODE = SMALLEST
