Well think about it this way: If you were having an all you can eat buffet, you'd eat as much as you could until you had no room left. It's pretty much the same, there's a limit, but one which is only reachable if you overuse the opportunity.
No, not all data sets have a mode but all data sets have a mean and median.
it gives you the adverage of all data represented
There is not a mean of a single number. To calculate a mean, you need a data set. The mean is given by the sum of all the data, divided by the number of pieces of data.
Well . . . data can be filtered. I have done it. That does not mean that all data is filterable.
Add it all together, and then divide it by the number of data entries that there are.
The mean=Adding all of the data and dividing by how much data you have.
It tells you the average of all of your data. So then you know about the answer to your question for your data.
you win
Not all the time
all the data added together
it means you clear all your history (recent information that you have done) and totally erase all your data
You take all the numbers in the data and add them. Then you divide by how many numbers are in the data. :)
