GRAVETTER_CH03_CENTRAL TENDENCY AND THE SHAPE OF THE DISTRIBUTION Flashcards
TRUE OR FALSE: If a distribution is perfectly symmetrical, the median, mean, and mode will have the same value.
TRUE.
TRUE OR FALSE: A bimodal distribution that is symmetrical will have the mean and median together in the center with only one mode.
FALSE.
There are still two modes. They are on each side of the mean and median.
TRUE OR FALSE: In skewed distributions, the three measures of central tendency will end up in relatively the same areas as in a symmetrical distribution.
FALSE.
There is a strong tendency for the mean, median, and mode to be located in predictably different positions.
TRUE OR FALSE: The mode in a skewed distribution splits the distribution in equal halves.
FALSE.
It does not divide the distribution into two equal halves.
THINK! In a skewed distribution, wat types of scores influences the mean and in which area?
The extreme scores in the tail.
TRUE OR FALSE: In both negatively and positively skewed distributions, the median is usually located between the mean and the mode.
TRUE.
