 Changes in median Here is how median is affected when we change units: If you add a constant to every value, the median increases by the same constant. Suppose you multiply every value by a constant. Then, the median will also be multiplied by that constant. Find the Median for 14, 16, 19, 21, 23 and 26. Then add 3 to every value and find the new median. The given set has an even number of value (N=6). So the median is the average of two middle numbers. $\frac{19+21}{2}=\frac{40}{2}=20$ So the median is 20. Now we add 3 to every value and find the new media: 17, 19, 22, 24, 26, and 29 The given set has an even number of value (N=6). So the median is the average of two middle numbers. $\frac{22+24}{2}=\frac{46}{2}=23$ So the median is 23. If we add 3 units to every value, then the median increases by 3 units. Find the Median for 14, 16, 19, 21, 23 and 26. Then multiply by 3 every value and find the new median. The given set has an even number of value (N=6). So the median is the average of two middle numbers. $\frac{19+21}{2}=\frac{40}{2}=20$ So the median is 20. Now we multiply by 3 every value and find the new media: 42, 48, 57, 63, 69, and 78 The given set has an even number of value (N=6). So the median is the average of two middle numbers. $\frac{57+63}{2}=\frac{120}{2}=60$ So the median is 60. If we multiply by 3 every value, then the median is multiplied by 3 units (60=3·20).
