Is the class interval where the median lies just the same as the median?
No.
The number in the middle in a ordered set numbers?
The median is the value which lies half way along the set when arranged in ascending or descending order.
What percent of the data in a normal distribution lies more than 2 standard deviations above the mean?
2.275 %
If y is a positive integer and the median of 3y y 5y 2y and 4y is 27 what is the value of y?
The median is the value that lies halfway along the series when arranged in ascending or descending order. When arranged in ascending order : y, 2y, 3y, 4y, 5y : the median is 3y. If 3y = 27 then y = 9.
What is the different between measures of center and measures of variability?
The answer lies in the question! The first lot measure where the centre of a distribution or observation lies while the second lot are a measure of the distance of individual observations from the centre.
Is the class interval where the median lies just the same as the median?
No.
What is the significance of the mean of a probabilty distribution?
It is a value around which the distribution lies.
What is the z value such that 50 percent of the total area lies to the right of the curve in a normal distribution?
The Z value is 0.
What is a line that lies far from the center of a distribution?
it is nothing
What percentage of the data set that lies above the second quartile?
50%. The second quartile is the median.
How did Harlow Shapley determine where the center of the galaxy lies?
by plotting the distribution of open clusters
In the Standard Normal Distribution 2.5 of the data lies above the standardized value of z?
No, they do not.
The Pearson's coefficient of skewness is a measure of distribution's symmetry?
It is a descriptive statistical measure used to measure the shape of the curve drawn from the frequency distribution or to measure the direction of variation. It is a measure of how far positively skewed (below the mean) or negatively skewed (above the mean) the majority (that's where the mode comes in) of the data lies. Useful when conducting a study using histograms. (mean - mode) / standard deviation. or [3(Mean-Median)]/Standard deviation
Find the standard deviation when the mean is 100 and 2.68 of the area lies to the right of 105?
z=x-u/s 2.68=.0268 in normal distribution = .07 .07=105-100/s s=71.4
The number in the middle in a ordered set numbers?
The median is the value which lies half way along the set when arranged in ascending or descending order.
Find the z-score for which 92 percent of the distribution's area lies between -z and z?
z = 1.75
What percent of the data in a normal distribution lies more than 2 standard deviations above the mean?
2.275 %
