Question
One problem with the range (R) as a measure of dispersion is that it:
is based on only the most extreme scores
ignores the most extreme scores
is very difficult to calculate
is very difficult to calculate
6) For variables measured at the nominal level, an appropriate measure of central tendency is:
the mode
the index of qualitative variation
the range
the average deviation
A.is based on only the most extreme scores
B.ignores the most extreme scores
C.is very difficult to calculate
D.is very difficult to calculate
Explanation / Answer
Answer to the question is as follows:
1. A is right. It is not difficult to calcualte. Just max-min
But as a measure of disperson it may fail as not many points will be extreme values.
6. A. the mode is the right indication/ approx measure of central tendancy
