Parameter |
Is a numerical measurement describing some characteristic of a population. |
|
Statistic |
Is a numerical measurement describing some characteristic of a sample. |
|
Quantitave data |
Consist of numbers representing counts or measurements. |
|
Qualitative ( or categorial or attribute) |
Data can be separated into different categories that are distinguished by some non-numerical characteristic. |
|
Discrete data |
Result when the number of possible values is either a finite (that is the number of possible values is 0, 1, or 2, and so on). |
|
Continuous (Numerical Data) |
Result from infinitely many possible values that correspond to some continuous scale gapes, interruptions or jumps.
|
|
The Nominal level of measurement |
Is characterized by data that consist of names, labels, or categories only. The data cannot be arranged in an ordering scheme (such as low to highs). |
|
Interval Level of measurement |
Is like the ordinal level, with the additional property that the difference between any two data values is meaningful. However, data at the level Do not have a natural zero point (Where none of the quantity is present). |
|
The ratio level of measurement |
Is the interval level with the additional property that there is also a natural zero, starting point (where zero indicates that none of the quantity is present). For values at this level, differences and ratios are both meaningful. |
|
The Nominal level of measurement |
Is characterized by data that consist of names, labels or categories only. The data cannot be arranged in any ordering scheme (such as low to high). |
|
Data are at the Ordinal level of measurement |
If can be arranged in some order, but difference between the data values either cannot be determine or are meaningless. |
|
The interval level of measurement |
Is like the ordinal level, with the additional property that the difference between any two data values is meaningful. However, data at this level do not have a natural zero starting point. |
|
The Ratio level of measurement level with the property that there |
Is also a Natural zero starting point (Where zero indicates none of the quantity is present). For values at this level differences and ratios are both meaningful. |
