I'm sorry, still couldn't understand this - could you please brief it... i thought, since the percentage value is upto 180%, the median will be 90%...? I understand that median is centeral tendency of the elements, but couldn't understand how it is 100 here
Good that you're pushing on this a bit more, because I often see that one of the biggest struggles with graphs is finding the median on them!
So the median of a set of numbers isn't the point halfway between the highest and lowest (or even halfway between the highest and lowest possible), it is the middle number when the values are placed in order (or the average of the middle two if there are an even number of terms).
For example, in the new set of numbers 1, 3, 3, 7, 10, the median is NOT going to be halfway between 1 and 10. The median will be the middle of this set, or 3.
If the set was instead 1, 3, 3, 6, 7, 10, then the median will be the average of the middle two numbers (3 and 6) - so the median is (3+6)/2 = 4.5.
Now back to this question! While it is true that the percentage values on the y-axis go from 0 to 180, the median doesn't care about that any more than it cares about the value of the highest or lowest dots. It only cares about what happens if you list out the values of the dots in order from smallest to largest and then find the middle one. So you could simply list out the estimated values for each metric in order from highest to lowest.
For
job satisfaction rating, the values increase from left to right, so start with the left-most and move right: 30, 40, 40, 45, 50,
55, 60, 75, 80, 85, 85 (the median = the middle = the dot at 55)
For
salary as % of median, the values increase from bottom to top, so start with the lowest dot and move up: 41%, 59%, 70%, 78%, 93%,
100%, 110%, 120%, 135%, 142%, 160% (the median = the middle = the dot at 100%).
But because you know that there are 11 employees, you don't actually have to list out everyone. You know that the median of the 11 people will be the 6th term from the highest or the lowest end (because there will be 5 terms on either side of it... 5+1+5 = 11. So instead of listing, you can just count to the 6th dot from left-to-right or from bottom-to-top depending on which metric you're finding the median for!
Hope this helps!
