Four scales of measurement are: nominal, ordinal, interval, and ratio.

a. What additional information is obtained from measurements on a ratio scale compared to measurements on an interval scale?
b. What additional information is obtained from measurements on an ordinal scale compared to measurements on a nominal scale?
c. What additional information is obtained from measurements on an interval scale compared to measurements on an ordinal scale?

The answer are (a) measurement on ordinary scale can be ranked, but on nominal scale observation cannot be ranked, (b)  on the interval scale measurement can be compared in terms of difference of magnitude, but on ordinary scale, observations cannot be compared in terms of magnitude (c) the point of zero is arbitrary and can be found in any where on the measurement of interval scale

Step-by-step explanation:

Explanation

(a) In nominal scale measurement, observations are classified but in ordinal scale measurement  observations are ranked

Therefore additional information of comparing ranking in observation when measurement are gotten from ordinary scale as compared to nominal measurement.

(b) In interval scale measurement  can be compared by different magnitude  because it is ranked, while ordinary scale measurement, observation can be ranked for comparison

For example the grade of student in a school are grouped under the ordinary scale of measurement due to the fact that Grade A is greater than B

Therefore we have extra information of contrasting observations based on magnitude differences when measurement are gotten form interval scale  as against  ordinary scale

(c) In the interval scale of measurement,  observations are compared in terms of magnitude differences. the point of zero is arbitrary and can found anywhere

For example if a person has no salary what this means is that he has rupes of zero (salary)

Then again, the additional information of the zero point of arbitrary is when measurement is gotten from interval scale. what this suggest is that none is in the scale of ratio

answer: it's upside down and i can't read it

step-by-step explanation:

answer: 1+1

step-by-step explanation: 1+1 is at least 2
