Question

For any Variance, the Standard Deviation is the squart roo. So,for a Variance 2, Standard deviation-V2 = 1.414. 3. If you use a graduated cylinder to measure the volume of water in milliliters (ml), what scale of measurement is that? 4. If you measure your body temperature using a Fahrenheit oral thermometer, what scale of measurement are you using? Your statistics computer program doesn't understand words, just numbers. You have already collected data on how many people own Japanese, versus American, versus European cars. But since your program doesn't understand those words you assign the numbers 1, 2 and 3 to the different car types. What scale of measurement is this? 5. Except for the 2 sex chromosomes, X and Y (which we won't include in this problem), there are 22 other human chromosomes that vary in length. You assign numbers to each chromosome based on its length (longest to shortest). What scale of measurement does this represent? 6.

Explanation / Answer

3) Ratio Scale: Ratio scales are very similar to interval scales where the difference between values is meaningful.. However, they also have meaningful zeros (zero weight means that weight does not exist). Thus the volume of water in millimeters measured using a graduated cylinder is an example of Ratio Scale as Physical scales of time, length and volume are ratio scales.

4) Interval scale: A interval scale has measurements where the difference between values is meaningful. In other words, the differences between points on the scale are measurable and exactly equal. They have no meaningful zeros. Degrees Fahrenheit are not ratio scales, because a temperature of 0 does not mean that “temperature doesn’t exist.” Therefore, body temperature using a Farenheit oral thermometer is an interval scale.

5) Nominal scale or Categorical: Data that can be put into categories. This set of data has no meaningful differences between values. eg: gender, civil status, nationality, religion. Here, the categories of each nominal variable do not indicate that one is superior or greater than the other. These are mainly classifications that separate one group from the other. Thus the labelling of American, Japaneese and European cars are an example of Nominal scale.

6) Ordinal Scale: This level of measurement depicts some ordered relationship among the variable’s observations. It is possible to rank order the different groups because each group shows attributes that are convincingly superior or greater than the other or vice-versa. Thus assigning numbers to each chromosomes based on their length is an example of ordinal scale of measuremnet.
