Coefficient of variation is a measure of relative variation. True or False?
True
What is measure of center?
the center of measure is mean mode median and range
Does variation mean range in math terms?
No. A range is one measure of variation. It is easy to find, but it is also a rather crude measure.
What is the prime measure of central tendency is the?
Median
When do you used the measure of central tendency?
Mean, Median, and Mode
Which measure of variation is appropriate when using the mean and which is appropriate when using the median?
When using the mean: the variance or standard deviation. When using the median: the range or inter-quartile range.
What are the criteria for choosing measure of central tendency and measure of variation?
Central tendency is measured by using the mean, median and mode of a set of numbers. Variation is measured by using the range, variance and standard deviation of a set of numbers.
What is the median is a measure of?
the median is the middle like 2,3,5,7,4,2.8. the median is 7 because it is in the middle.
What is the measure of center?
the center of measure is mean mode median and range
Coefficient of variation is a measure of relative variation. True or False?
True
What is measure of center?
the center of measure is mean mode median and range
Does variation mean range in math terms?
No. A range is one measure of variation. It is easy to find, but it is also a rather crude measure.
Why is the median a more stable measure of central tendency than the mean?
in general,mean is more stable than median but in the case of extreme values it is better to consider median a stable measure than mean.
What is measure of variation?
A measure of variation, also called a measure of dispersion, is a type of measurement that details how a set of data is scattered from a central or neutral point of origin. Range, variance and standard deviation are three measures of variation that are commonly used.
What is the median of 21 liters of water?
The median of a single measure is itself: so 21 litres of water!
Does the median have to be a number?
Yes, the median is always a number. For qualitative data, use the mode for a measure of center.
What is the prime measure of central tendency is the?
Median
