<prompt> If mean is less than the median, than the data is said to bePositively skewedNegatively skewedEquitable distributionNormal distribution  <response>: Ans. is b i.e. Negatively skewed Relationship among the three measures of central tendency ie mean, median and mode in a skewed curve is an oft repeated question.Lets first see what skewed distribution curve is. An asymmetrical distribution curve can be of two types:Positive skewed distribution curveNegative skewed distribution curvePositive or right and negative or left skewed curves are recognized by the location of the tail of the curve not by the location of the hump - a common errorPositive or Right skewed distribution curve there curves have a relatively large number of low scores and a small no of very high scores the mean lies towards the extreme right of the curve Negative or left skewed distribution curve.there curves have a large number of high scores and a relatively small number of low scores the mean lies towards the extreme left of the curve.Now lets see the measures of central tendency.Modeis the most frequently occurring valueit lies at the peak of the hump.Meanis the arithmetic averageit is greatly influenced by the relatively small number of very high or very low scoresit liestowards the extreme right in a right Positive distribution curve andtowards the extreme left in a left negative distribution curve.Medianis the middle valueit lies bw the mean and mode dividing the curve into two equal halves.Relationship bw the measures of central tendency In a symmetrical curveMean Median Mode In a Positive Right skewed curveMean Median Mode In a Negative left skewed curveMean Median Mode
