Why standard deviation is best measure of dispersion?
standard deviation is best measure of dispersion because all the data distributions are nearer to the normal distribution.
Is length in feet quantitative or qualitative data?
Anytime you are able to measure something, it is quantitative data. Qualitative data represents the quality of something which cannot be measured.
Can frequency distribution contain qualitative data?
frequency distribution contain qualitative data
If a great many data values cluster to the left of a data distribution which then tails off to the right the distribution is referred to as?
It is a positively skewed distribution.
What is a normal data set?
A normal data set is a set of observations from a Gaussian distribution, which is also called the Normal distribution.
What measure of dispersion is used with bimodal distribution?
Central tendency is used with bidmodal distribution. This measure if dispersion is similar to the median of a set of data.?æ
What does the mode tell you about the distribution of a set of data?
It tells you that that number has the most part of everything.
Which measure of central tendency best describes the data set without an outlier?
The mean may be a good measure but not if the data distribution is very skewed.
What does mean deviation tells us about the data?
It is a measure of how variable the data is. The average distance from the average.
Why is the mode not used very much as a measure of central tendency?
The mode is the value with the most data. Unfortunately it tells you nothing about the rest of the distribution. The mean and median provide more useful information in most situations.
Is the mass of an orange a qualitative data?
no, it's quantitative data. Quantitative data is something you can measure - weight, length, height, time etc. Qualitative data is something you can't measure e.g. how happy people are, what people feel about something
Why standard deviation is best measure of dispersion?
standard deviation is best measure of dispersion because all the data distributions are nearer to the normal distribution.
What is the definition of spread math?
Spread, in the context of a probability distribution, is a measure of how much the data vary about their central value.
Is length in feet quantitative or qualitative data?
Anytime you are able to measure something, it is quantitative data. Qualitative data represents the quality of something which cannot be measured.
When is finding the average not useful?
There is no meaningful average wen data are categorical (qualitative). Also, the arithmetic mean is not a good measure of central tendency when the data distribution is skewed.
What is the between skewness and kurtosis?
While skewness is the measure of symmetry, or if one would like to be more precise, the lack of symmetry, kurtosis is a measure of data that is either peaked or flat relative to a normal distribution of a data set. * Skewness: A distribution is symmetric if both the left and right sides are the same relative to the center point. * Kurtosis: A data set that tends to have a distant peak near the mean value, have heavy tails, or decline rapidly is a measure of high kurtosis. Data sets with low Kurtosis would obviously be opposite with a flat mean at the top, and a distribution that is uniform.
Can frequency distribution contain qualitative data?
frequency distribution contain qualitative data
