Why is the median a more stable measure of central tendency than the mean?
in general,mean is more stable than median but in the case of extreme values it is better to consider median a stable measure than mean.
Why calculate for the mean and median in relation to a sample?
Both the mean and median represent the center of a distribution. Calculating the mean is easier, but may be more affected by outliers or extreme values. The median is more robust.
Does all statistical data have a mean median or mode?
It depends on the definition of mode. If mode is simply the most frequently occurring outcome and more than one outcome in the sample space is allowed to be the mode, then all datasets do have a mean, median, and mode.
Advantages and disadvantages of using arithmetic mean?
"The advantage is that the mean takes every value into account. A disadvantage is that it can be affected by extreme values. " The mean or more properly the "arithmetic mean" of a sample will eventually approximate the mean of the distribution of the population as the sample size increases. If the population distribution is skewed (not symmetrical), the mode and median will not provide an estimate of the mean, even as the sample size becomes large.
When is the median more useful than the mean?
When the distribution has outliers. They will skew the mean but will not affect the median.
What is more accurate mean or median?
Technically the mean is more accurate, but it is not always a true representation, when you have a number that is way out of proportion with the rest of the numbers. That is when the median is more useful. See the related question below.
What is median if even?
In maths, the median is connected with the mode, mean. Help learn theese by singing a song, more of a chant though. Mode most Median middle Mean add up and divide Mode most Median middle Mean add up and divide!!
What is the mean median and mode of 3456 560 435 456?
The mean is 1226.75. The median is 508. There is no mode as no number occurs more than any other.
Why is mean more accurate tan median?
cos mean is the average and median is putting them in ascending order and selecting the middle one example: 23 ,24 ,27 ,28 ,29 mean= 26.2(it's like it's in the middle) Median= 27 now, which do you think is more accurate??:)
Is the mean or median more accurate?
None of them is "more accurate". They are answers to two different questions.
Is the median affected by the mean?
The median is the value which seperates the upper and lower half of a set of numbers. The mean is the average value between two or more numbers. In calculating a set of numbers, specifically a set of averages, the median may indeed be effected by the mean.
What is the mean median and mode for 1 9 4 7 5 3 16 11?
