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.

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.


What is the appropriate measure of central tendency for age?

The appropriate measure of central tendency for age is the median. This is because age is a continuous variable and can have outliers or extreme values, which can skew the mean. The median provides a more robust estimate of the center of the distribution.


The measure of central tendency that is most affected by a few large or small numbers is?

The mean is the measure of central tendency that is most affected by a few large or small numbers. The median is more robust for extreme values.


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 do we study the median?

The median is a more robust measure than the average, which means it is more resilient to the effects of outliers in your dataset.


What is the purpose of the median?

The median is one way of three, of measuring the central tendency of a bunch of objects. Each of the three measures has plusses and negatives. They are: the mean (or average: add the values and divide by the population number) The mode ( or value - can be several where more individuals are found than at other values, i.e. a peak or popular value) the median (or value which divides the whole bunch into two similar parts - as many bigger as smaller valued) EXAMPLE: there is a group with the following values: ten are valued at 1 nine are valued at 3 one is valued at 1000. The mean is [1000 + 9X3 + 10X1] / 20 = 51.85 The mode is 1, the next mode is 3 The median is 2 (with ten below, and ten above)


What does mean median in math?

The term median refers to an average value indicated by the middle number or numbers in a series. It can be different from the "mean", which is the average value found by adding the numbers and dividing.Where there is an odd number of values, the median is the central (middle) value.For example, in the set [ 1, 2, 7, 50, 100 ] the median value is 7. There will be as many values less than the median as there are greater than the median. (if you have duplicate values, more than one may be equal to the median)Where there is an even number of values, the median is the mean (average) of the two central values. For example, in the set [ 1, 2, 7, 9, 50, 100 ], there are two central values, 7 and 9. The median would be 8, and again there will be as many values less than the median as there are greater than the median.To find the median : put your numbers in order by their value, and count the number of values. Divide the number of values by two to locate the center value or values. Where the number of values is even, add and average the two in the middle.Example : values [ 27, 18, 3, 99, 55, 1, 16 ]Ordered set : [ 1, 3, 16, 18, 27, 55, 99 ]Median : 18


If you get more than one median what do you do?

There is only one median in a set of values. If it is an odd amount of values, the median is the middle number. If there is an even amount of numbers, the median is the value halfway between the two middle numbers. So, in 1, 2, 3; the median is 2. In 1, 2, 3, 4; the median is 2.5, as that is halfway between 2 and 3.


What if there is more than one of a median?

In statistics, the median is defined as the middle value in a data set when it is ordered from least to greatest. If there is an even number of observations, the median is calculated as the average of the two middle values. In cases where the data set has repeated values, the median remains a single value representing the central tendency, regardless of how many times certain values appear. Thus, while there can be multiple modes (most frequently occurring values), the median itself will still be a unique value.


Can a data set have more than one median?

No, a data set cannot have more than one median. The median is defined as the middle value of a sorted data set, or the average of the two middle values if the data set has an even number of observations. While a data set can have repeated values, the median itself remains a single value that represents the central tendency of the data.


Is there ever more than one median?

No, there is never more than one median in a data set. The median is defined as the middle value when the data is arranged in order. If the data set has an odd number of observations, the median is the single middle value. If it has an even number of observations, the median is the average of the two middle values, which also results in a single value.


What is the Median of 8 5 9 2 2?

The median is 5, because two values (2 and 2) are less than 5, and an equal number of values (8 and 9) are greater than 5. Generally speaking, the median is more informative than the average (mean), although a proper calculation of a "typical value" of a list of values depends on what the typical value will be used for.
