What are the advantages and disadvantages of median?
Median cannot be used for qualitative data (a mode can).The sampling distribution of the median is complicated (the mean is well studied).Median can usually be used for data that can be ordered without there being a ratio scale. For example, "small-medium-large", or "very negative-negative-neutral-positive-very positive". A mean cannot be calculated without arbitrarily assigning a numerical value to the terms.A median is not dependent on all the values which means that it is not distorted by outliers (extreme values).It is easy to find the median value from cumulative frequency charts.
Why is the answer in subtraction called the difference?
Its because you are finding the "difference" between the two numbers.
What is difference between continuous and ordinal variable?
A continuous variable is one which can take any numerical value over some interval. An ordinal variable is one that can take non-numerical or categoric values which can be put into some logical order but where the difference between successive categories cannot be quantified. One example may be Small-Medium-Large, or a popular one among opinion pollsters: Disagree Strongly-Disagree-Agree-Agree Strongly.
What is the median of 105 53 76 91 120 61 55 98 61?
Alright, buckle up buttercup. To find the median, you first need to arrange the numbers in numerical order. So, after doing some light organizing, the numbers look like this: 53, 55, 61, 61, 76, 91, 98, 105, 120. Now, since there are 9 numbers, the middle one (the median) is the 5th number, which in this case is 76. Voilà, that's your median!
What is the difference between one thousand nine hundred and ninety nine and three thousand and three?
Well, darling, the difference between 1999 and 3003 is a whopping 1004. Yes, you heard me right, 1004. It's simple math, honey. Just subtract 1999 from 3003 and you'll get your answer. So, there you have it, a 1004 difference between those two numbers.
What can the difference between mean and median values infer. If the mean is 8 655.7 and the median -8 653.0?
First, I will give an example, similar to your question: -11000 -9000 +44000 mean = 8,000 and median = -9000. Symmetrical distributions after infinite sampling will show no difference in mean and median. Large differences are possible with small sample sizes even with symmetrical distributions. If the sample is large and the difference is large, this infers that the distribution is asymmetrical. The skewness of the distribution can be calculated.
Why is the median more robust for extreme values?
The median is the middle of average of the middle two values from the ordered set of observations. If the extreme values are genuine then they will have no effect on the median. If they are incorrectly measured or recorded data then they may affect the position of the middle of the ordered set of data. However, since there can only be a small number of outliers, their effect on the median will be small.
Is median always part of the data set?
yes* * * * *No. If you have a small, even number of observations, the median is the average of the two middle values. This will usually NOT be part of the data set.
What is the difference between the esophagus and the small intestines?
what is the difference between the esophagus and the small intestines
Is median used for when there is a wide range of numbers?
If the wide range is evenly spread between the very small and the very large (the distribution is symmetric) then there is not much to choose between the median and the mean. If not, the median will have some advantages as a measure of central tendency.
If the difference in electronegativity values between two atoms is more than 2 nonpolar covalent bonds generally form?
That statement is incorrect. If the difference in electronegativity values between two atoms is more than 2, it typically indicates that ionic bonds will form, not nonpolar covalent bonds. Nonpolar covalent bonds form when the electronegativity difference is very small or negligible.

What is the difference between a club and a society?
Clubs are small groups with clearly defined labels and rules. Societies are larger groups of people, such as a country that share values but are different.
What is the difference between a revolution and a small change?
The difference is that a change forms.
What is the value of the data point in the middle of a set of data when the data are arranged in order from smallest to largest?
It is the median, which is an indication of the central tendency of a distribution.The main advantages of the median are that it is an observed value. The mean may not be a possible outcome - eg 2.4 children in the average family! How do you get 0.4 child?The median is not affected by outliers (extreme values) which could be due to errors.The median can be calculated for ordered data (eg data categorized as small, medium, large) even if the difference between small and medium is not the same as the difference between medium and large.The other two common measures of the central tendency of a data set are the mean and the mode. The mean is what is commonly referred to as the average. It is the most commonly used indicator of central tendency. If you have n values, add them up and divide the sum by n and you have the mean.The mode is the other common indicator and it is simply the most frequently occurring value in the data set. Modes are nice for dealing with categorical data.An important part of statistics is knowing which measure of central tendency to use for a particular data set.
