    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 !
