The median is the middle value (or mean of the two middle values if there are an even number of values) and so is unaffected by an increase in the highest data value. It is still 90.
The mean was 95, so the total for the data set was 95x100 = 9500. If the highest data value is increased by 200, the data set total is also increased by 200, giving a new data set total of 9500 + 200 = 9700, so the new mean is 9700/100 = 97.

What is a median?
The median of a set of values is the quantity at the mid-point, when the values are in ascending numerical order. For example, the median of the numbers 1, 3, 5, 7, 9 is 5. When there is an even number of terms, the median is the mean of the middle two terms. For example, the median of the numbers 1, 3, 5, 7 is 4.
What is the middle value of a data set when the values are written in numerical order?
Median
Do extremely high or low scores affect the value of the median?
No, extremely high or low values will not affect the median. Because the median is the middle number of a series of numbers arranged from low to high, extreme values would only serve as the end markers of the values.
What is the 5 number summary for a box and whisker plot?
Min- the lowest value Q1- the median number between the actual median and the min Median- the "middle" number in the dataset Q3- the median number between the actual median and the max Max- the highest value
Mean equals 26.8 and median equals 27.9 then what is mode?
A specific value for the mode cannot be given with the information provided. The arithmetic mean = Sum of all the values ÷ The number of values. The median is the value which lies halfway along the series when arranged in ascending or descending order. The mode of a set of values is the value which occurs most frequently.
Median of a data is 20 If each is obesrvation in the data is increased by 2 then what is the new median. Need descriptive answer?
The median of a set of values or data is the value which lies half-way along the series when it is arranged in ascending or descending order. If there are an even number of data entries then the median is the mean of the middle two values. 1) If there are an odd number of values then there will be the same number of values higher than the median as there are below the median. An increase of 2 to each member of the set does not affect the order and the existing median remains the middle placed value So, 20 becomes 22. 2) Where there are an even number of values then both middle values will increase by 2 (a total increase of 4). The median is the mean of these two values and therefore increases by 2 (as the increase of 4 ÷ 2 = 2). So, 20 becomes 22.
What is the median and range for this set of weights 30 pounds 49 pounds and 52 pounds?
The median number is the one situated in the middle when all the values are in order. In this instance, the median of 30, 49, and 52 is 49.The range of the values is equal to the difference between the highest and the lowest value. In this instance, the difference between the highest and lowest value is 52 - 30 = 22 lbs.
What if the median has 6 values how do you work it out?
A median can have only one value.
What is the median of a single value?
The median is the number in the middle. You find the median, by putting the values in order from lowest to highest, then find the number that is exactly in the middle. If you only have a single value, one could argue that it is in the middle. That would make the single value the median. One could also argue that there no numbers on either side to the definition makes no sense and there is no median of a single value.
What is the median of a set of values?
the median is a value of which half of all the values are less than, and half of all the values are greater than.
Can average be regarded as best for all times all data?
No. The three averages are mean, mode and median. Mean is the total values divided by the number of values; mode is the number occurring most often; median is the middle value (or the value halfway in between the two middle values) when all values are in order. What you have described is basically the maximum (highest/best value) times the number of values, which has no major use in statistics.
What is the middle value or average of the two middle values in a data set?
The middle value in a data set is the median. If there are an even number of values in the set, you average the middle two values to get the median.
Is the mean and median similar?
The Mean is the average of a given set of values. The Median is the value that has the same number of smaller values than the number of higher values, it is in the middle of them. In a symmetrical distribution the Mean is equal to the Median. In an asymmetrical distribution they have different value.
What does the MEDIAN function do in Excel?
The median is a form of average. It finds the middle value of the list of values in numerical order if there is an odd number of values. If there is an even number of values, if uses the value halfway between the two middle values.The median is a form of average.

What is median-median point?
It's the point for a set of points whose x-value is the median of all the given x-values and whose y-value is the median of all the given y-values. For example: (1,2) (2,1) (3,5) (6,4) (10,7) the median-median point would be (3,4)
How do you find the median if two numbers are in the middle?
You take their average. With an odd number of values, there's no problem, say you have 7 values and you've ranked them lowest to highest. The fourth value is your median. Now with 8 values, add your fourth and fifth together and divide by 2.
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
