C4 Quiz

• The median is the score point above and below which an equal number of cases fall.
• The mean of a distribution of scores for a very easy test is 24.3. Which of the following is most likely to be the median?  26.2
• If the mean is 130 and the median is 140, it seems likely that the distribution is negatively skewed.
• The main advantage the arithmetic mean has over the median and mode has to do with response to mathematical manipulation.
• The mode is the most appropriate measure for qualitative data.
• For a symmetric distribution of 10 scores the mean is calculated to be 32.6. Later it is learned that John's recorded score of 28 really should be a 35. Correcting this error will change the calculated value of the mean and the median.
• For a highly positively skewed distribution of scores, the mean is calculated to be 45.1. Later it is learned that John's recorded score of 47 really should be a 50. Which of the following is most likely to remain the same after correcting this error? mode and median.
• If one score in a distribution is changed to another value, it is certain that, according to raw score calculation. the mean has changed.
• If scores are expressed in terms of the amount by which they deviate from a measure of their central tendency, the sum of the negative deviations will equal the sum of the positive deviations when deviations are taken about the mean.
• If the mean of a distribution of scores for a very easy test is 24.3, then 26.2 is most likely to be the median.
• The main advantage the arithmetic mean has over the median and mode has to do with response to mathematical manipulation.
• For a highly positively skewed distribution of scores, the mean is calculated to be 45.1. Later it is learned that John's recorded score of 47 really should be a 50. The mode and median are most likely to remain the same after correcting this error.
• The median is the score point above and below which an equal number of cases fall.
• The highest point of a frequency curve is most closely associated with the mode.
• If the mean is 130 and the median is 140, it seems likely that the distribution is negatively skewed.
• The mode is the most appropriate measure for  qualitative data
• For a symmetric distribution of 10 scores the mean is calculated to be 32.6. Later it is learned that John's recorded score of 28 really should be a 35. Correcting this error will change the calculated value of the mean and the median.
