?? ?? ?? ?? + Measures of location and spread A measure of spread is a value which indicated how spread out the data set is. Examples include the range and interquartile range. The range is the difference between the largest and smallest values, and measures the spread of all the data The interquartile range is the difference between the upper and lower quartiles, and measures the spread of the middle 50% of the data The interpercentile range is the difference between 2 given percentiles 2D
?? ?? ?? ?? + Measures of location and spread Mass, m (t) Frequency A measure of spread is a value which indicated how spread out the data set is. Examples include the range and interquartile range. 13 4.0 ? < 4.5 23 4.5 ? < 5.0 31 5.0 ? < 5.5 The range is the biggest possible value subtract the smallest possible value 34 The table to the right shows the masses (tonnes) of 120 African elephants. 5.5 ? < 6.0 19 6.0 ? 6.5 6.5 - 4.0 = 2.5 Find estimates for: a) The range b) The interquartile range c) The 10th to 90th percentile range ?.? 2D
