- In this video I explain how to find the precise median for a continuous variable with many repeated scores. I walk through an example of this that can be solved visually, then use this example to derive the formula for an interpolated median.
nice explanation
This saved me ty so much
Glad it was helpful!
Very useful explanation, just that I am having trouble with using the formula for my statistics problem. Thank you for your explanation.
You're welcome, let me know if you're still having any trouble and I can try to add more explanation here!
I have a question: Is h always going to be 1?
No, not necessarily, 1 would be common but h will be whatever the class interval of the measurement is. In this example we measured to the nearest whole second, so it was a class interval of 1 and each box represents 1 second.
But we could have a different class interval, meaning that instead of each box in the diagram representing 1 second, it would represent some other set value, say 4 seconds. We would then need to remember that if we're taking 1/4 of a 4-second box, that represents 1 second. Or if the class interval were 10 then a quarter of a box would represent 2.5 seconds. Hope this helps!
