origins of statistical averages
Hi;
I'm trying to find out what the three measures of central tendancy originate from
ie what does the mean,mean I know how to calculate it but what does it mean,Also
I know how to work out the mode but what does mode mean and the same for medien?

Hope that makes sence?

Thanks.

Re: origins of statistical averages
Is this, you want to know the definitions, or you want to know how when and why we use them??

A good technique I was taught by, was separating data into discrete and continuous data. Simply making these distinctions makes understanding statistics a whole lot easier.

Generally we use mode to calculate averages for discrete data. We use mean for normalised/normal data (bell curve) and we use median when there is skewness.

Hope that helps.

I understand. They are hard to define.

Best I got is; All three of them are measurements of 'averages', but they differ in their relevance to certain data types, as I mentioned above.

Sorry !
