Is range a measure of central location?
No, it isn't. Mean, median, and mode are the three most common measures of central location (although there are others). These measures of central location are attempts to find the middle value of a range.
3 Give a brief note of the measures of central tendency together with their merits and Demerits Which is the best measure of central tendency and why?
ANS: Measures of central tendency will quantify the middle of the distribution. The measures in case of population are the parameters and in case of sample, the measures are statistics that are estimates of population parameters. The three most common ways of measuring the centre of distribution is the mean, mode and median.In case of population, the measures of dispersion are used to quantify the spread of the distribution. Range, interquartile range, mean absolute deviation and standard deviation are four measures to calculate the dispersion.The measures of central tendency and measures of dispersion summarise mass data in terms of its two important features.i. With respect to nature of data to cluster around a central valueii. With respect to their spread from their central valueArithmetic mean is defined as the sum of all values divided by number of values.Median of a set of values is the middle most value when the values are arranged in the ascending order of magnitude.Mode is the value which has the highest frequencyThe measures of variations are:i. Range (R)ii. Quartile Deviations ( Q.D)iii. Mean Deviations (M.D)iv. Standard Deviations (S.D)Coefficient of variation is a relative measure expressed in percentage and is defined as:CV in %=
Which is the most accurate of mode mean median and range?
Accuracy depends on what you are trying to measure.As a measure of central tendency, the range is totally useless because it is not a measure of central tendency. As a measure of spread (dispersion), it is the most accurate because it is the only one that measures spread: the other threee are totally useless.With nominal data, the median and mean are not defined and so cannot be accurate.And so on.Accuracy depends on what you are trying to measure.As a measure of central tendency, the range is totally useless because it is not a measure of central tendency.

What shapes are most stable?
Triangle
What is the difference between arithmetic mean and mode?
The mean, median, and mode are all measures of central tendency. For symmetrical distributions they all have the same value. For assymetrical distributions they have different values. The mean is the average and the mode is the most likely value.
When is it the most appropriate time to use b Measures of Central Tendency?
The answer depends on what the "b" measures are and how they differ from the "a" measures and also "c" and other subsequent measures.
Is range a measure of central location?
No, it isn't. Mean, median, and mode are the three most common measures of central location (although there are others). These measures of central location are attempts to find the middle value of a range.
What measure of central tendency is most stable from sample to sample?
Statistically speaking, the mean is the most stable from sample to sample. Whereas, the mode is the least stable statistically speaking from sample to sample.
Which scale in WAIS- III is the most stable measure of intelligence?
The vocabulary subtest: The ability to define words is not only one of the best single measures of intelligence but also the most stable.
Why is that central star should not flare violently?
Because it is in its most stable part of its life.
Which of three three measures of central tendency is most affected by extreme scores.?
mean
Which of the arithmetic mean median and mode are resistant measures of central tendency?
Of these three, the median is most resistant.
What measures of central location is affected most by extreme values?
The mean is most affected. Mode and Median are not influenced as much by outliers.
Which of three three measures of central tendency is most affected by extreme scores?
Of the mean, median and mode the mean would be most affected.
What measure of central tendency would be most useful in describing the gender of a sample?
Since gender is a qualitative variable, the mode is the only one of the main measures of central tendency.
What are the four measures of central tendency?
The four measures of central tendency are mean-also called average, mode-the most frequently occurring numerical, median-the middle number after arranging all data from lowest to highest numerical and lastly standard deviation-root-mean-square or square-root of the variance. These are the 4 measure of central tendency.
What are the differences between the central bank of Nigeria and world bank?
central bank perform various actions but its most important job is to make certain that the national currency and money supply remain stable
