What is positional average?
Median is a positional average that gives the value located in the centre of the given statistical distribution.
What determines numerical measures of center and spread are appropriate for describing a given distribution of quantitative variable?
The choice of numerical measures of center (mean, median) and spread (range, variance, standard deviation, interquartile range) depends on the distribution's shape and characteristics. For symmetric distributions without outliers, the mean and standard deviation are appropriate, while for skewed distributions or those with outliers, the median and interquartile range are more robust choices. Additionally, the presence of outliers can significantly affect the mean and standard deviation, making alternative measures more reliable. Understanding the data's distribution helps ensure that the selected measures accurately represent its central tendency and variability.
What is the mode and median?
Both median and mode are the statistics formulas, Median is called mid value of the given data and mode is the value which occure repetedly in the given data.
How can you calculate median?
The median is the middle number of any given set when they are in order, least to greatest. If there is an even number of values, the median is the average of the middle two. Ex. (10, 17, 20, 45, 68) The median is 20.
What is a skewed question?
A skewed question is one that is phrased in such a way that a certain answer is more likely to be given. People use questions like this when they are trying to prove or disprove something, and want to show that other people to agree with them based on statistics or polls.
Is the mean and median similar?
The Mean is the average of a given set of values. The Median is the value that has the same number of smaller values than the number of higher values, it is in the middle of them. In a symmetrical distribution the Mean is equal to the Median. In an asymmetrical distribution they have different value.
What is positional average?
Median is a positional average that gives the value located in the centre of the given statistical distribution.
What determines which numerical measures of center and spread are appropriate for describing a given distribution of a quantitative variable?
The choice of numerical measures of center and spread depends on the distribution's shape and the presence of outliers. For normally distributed data, the mean and standard deviation are appropriate, while for skewed distributions, the median and interquartile range (IQR) are preferred. Additionally, if there are significant outliers, robust measures like the median and IQR provide a more accurate representation of the data's central tendency and variability. Thus, understanding the distribution's characteristics is key to selecting suitable measures.
Median formula for continuous frequency distribution?
If you will let me assume that the probability density function (pdf) is absolutely continuous over its support then the median is given as the integral from -inf to the median of the pdf over that support = 1/2.

How do you find missing frequency if median and mode are given?
How do you find missed frequency if median and mode are given
How do you find the value of x in a trapezoid given the median?
Given the median and trapezoid MOPN, what is the value of x?
What is the shape of a frequency distribution with an arithmetic mean of 12000 pounds a median of 12000 pounds and a mode of 12000 pounds?
The frequency distribution is likely to be symmetrical and bell-shaped, resembling a normal distribution. Given that the mean, median, and mode are all equal at 12,000 pounds, it suggests that the data is centered around this value with a balanced spread on either side. This indicates that the distribution has a single peak at the center, with a consistent frequency of values around the mean.
What is the mode and median?
Both median and mode are the statistics formulas, Median is called mid value of the given data and mode is the value which occure repetedly in the given data.
What is a median of light?
The median of light refers to the midpoint of a distribution of light intensity or brightness in a given context. In terms of physics, it can also relate to the median wavelength in a spectrum of light, which represents the wavelength at which half the total light is of shorter wavelengths and half is of longer wavelengths. In photography or imaging, it might refer to the median value of pixel brightness in an image, useful for analyzing exposure levels.
What is need of skewing?
Skewing in mathematics deals with statistics and with the averages of a given set of numbers. When talking about skewing, the group of numbers is usually skewed to the left, meaning most of the data falls below the median, or to the right, making most of the data above the median. Skewing can be caused by pieces of the data being very high above or below the rest of the data.
What is median-median point?
It's the point for a set of points whose x-value is the median of all the given x-values and whose y-value is the median of all the given y-values. For example: (1,2) (2,1) (3,5) (6,4) (10,7) the median-median point would be (3,4)
