If you have an even set of data then there are two middle numbers or medians. Average those two and create a median.
Example:
2,3,4,7,9,10
4 and 7 are in the middle.
(4+7)/2=5.5
5.5 is the median even though it is not one of the numbers in the data set.
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.
the new median is the same as that of old one. i.e 20 * * * * * If every observation is increased by 2, the new median is 2 more than the old 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.
yes, depending on what your numbers are, you would need for one to be higher and one lower than your current median, it's always the number in the middle or the average of the 2 middle if it's an even amount of variables.
The median can be found out by drawing a perpendicular to the x-axis from the intersection point of both the ogives
No and a single number cannot have a median either you need a series (at least two) to have a median.
the new median is the same as that of old one. i.e 20 * * * * * If every observation is increased by 2, the new median is 2 more than the old median.
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.

When the distribution has outliers. They will skew the mean but will not affect 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.
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.
Yes. If the predominant data are higher than the median, the mean average will be higher than the median average. For example, the median average of the numbers one through ten is five. The mean average is five and one-half.
In 2013, the median family income for white families was about $28,000 more than that of Latino families.
Median is the middle number in a group of numbers. If there more than one middle number, the median is either shown as average of the two numbers in the middle or shown as both the numbers. The median in 23 24 26 29 is 25 or {24;26}.
the intersection of less and more than ogive gives us the median of the following data.. but the median is not accurate as we draw the free hand cumulative graph..
