Median of a data is 20 If each is obesrvation in the data is increased by 2 then what is the new 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.
If you have more than one median what do you do?
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.
What is the median of two and one half?
The median of a data set comprising only one value is that value. So the median of 2.5 is 2.5.
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.
What is the median of 14?
With just one data point, the mean, median and mode are all the same as the data point itself. In this case, 14.
Can there be more than one median in a data set?
No.There is only 1 middle value.If there are an odd number of elements in the data set, the median is the middle one;Otherwise there are an even number of elements in the data set and the median is the mean average of the middle two (add them together and divide by 2).The median value can occur more than once in the data set, eg in {2, 5, 5, 5, 6, 7} the median is 5 ((5 + 5)/2 = 5) with a frequency of 3, but it is still only one value.
If you have more than one median what do you do?
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.
Can a mean average ever be higher than a median average?
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.
What do you do if theres two median and one is x?
One set of data can have only one median.
A single, extremely large value can affect the median more than the mean?
A single, extremely large value can affect the median more than the mean because One-half of all the data values will fall above the mode, and one-half will fall below the mode. In a data set, the mode will always be unique. The range and midrange are both measures of variation.
Can there be more than one median to a number?
No and a single number cannot have a median either you need a series (at least two) to have a median.
What is the median of two and one half?
The median of a data set comprising only one value is that value. So the median of 2.5 is 2.5.
Is it true that the median is always one of the data points in a set of data?
No, it is not necessarily true that the median is always one of the data points in a set of data. The median is found by arranging the data in numerical order and selecting the middle value. This value might be one of the data points, but it could also be the average of two data points if there is an even number of values in the set.
Advantages and disadvantages of median in statistics?
The median is advantageous because it is not influenced by extreme values, making it a robust measure of central tendency for skewed data sets. It is also easy to interpret and calculate. However, the median may not accurately represent the true center of a dataset if the data is heavily skewed or if there are outliers present. Additionally, the median may not be as efficient as the mean for certain statistical calculations due to its lack of sensitivity to all data points.
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.
Can one research test more than one hypothesis?
Yes, if the data collected will relate to more than one of them.
How do you find the missing number in a data set if there is no mean?
If there is no mean it is very rare that you will be able to find a missing number. Potentially if you have other numbers and you have a mode you can deduce the missing number by using the mode (if there needs to be one more of a certain number or a certain number cannot be increased in its count of numbers i.e. you can't have more 6's to maintain the current mode).
