What else can I help you with?
Is the class interval where the median lies just the same as the median?
No.
Why does mean lie to left of median in left skew data?
In left-skewed data, the distribution has a longer tail on the left side, which pulls the mean down more than the median. The mean is affected by extreme low values, leading it to be lower than the median, which represents the middle value of the dataset and is less influenced by outliers. As a result, in left-skewed distributions, the mean lies to the left of the median.
What is a median of the lower half of a set of data is called the?
The median of the lower half of a set of data is called the first quartile, often denoted as Q1. It represents the value below which 25% of the data lies and effectively divides the lowest 50% of the dataset into two equal parts. This measure is useful in understanding the distribution and spread of the lower portion of the data.
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.
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 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 the significance of the mean of a probabilty distribution?
It is a value around which the distribution lies.
What is a line that lies far from the center of a distribution?
it is nothing
What is a median of the lower half of a set of data is called the?
The median of the lower half of a set of data is called the first quartile, often denoted as Q1. It represents the value below which 25% of the data lies and effectively divides the lowest 50% of the dataset into two equal parts. This measure is useful in understanding the distribution and spread of the lower portion of the data.
What percentage of the data set that lies above the second quartile?
50%. The second quartile is the median.
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
In the Standard Normal Distribution 2.5 of the data lies above the standardized value of z?
No, they do not.
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 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
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.
