What is the median of 2 3 4 5 7 9?
When there is an even number of data items the median is the mean average of the middle two. → median of {2, 3, 4, 5, 7, 9} = (4 + 5)/2 = 9/2 = 4.5
How do you find the median of 4 numbers with 2 of those numbers being the same?
The fact that two of the four numbers are identical in no way changes the way you would find the median. When finding the median of a set of data, you must sort the data from highest to lowest (or lowest to highest). The data point right smack in the middle is the median. If there is an even number of data points -- as is the case here -- you must take the average of the two points in the middle. Let's say these are your data: 10, 10, 6, 3. The median is the average of 10 and 6, or 8. If your data is 10, 6, 6, 3, then the median is 6. If it's 10, 6, 3, 3, the median is 4.5 (the average of 6 and 3).
What is the median and mean1 1 2 2 2 3 3 3 3 4 4 4 5 5 6 7?
The data {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7} has: Median: Thee are 16 data items, so the median is the mean average of the middle two, ie the 8th and 9th numbers: median is (3 + 3) / 2 = 3 Mean: (1 + 1 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 4 + 4 + 4 + 5 + 5 + 6 + 7) ÷ 16 = 55 ÷ 16 = 37/16 = 3.4375
Why is number 1 the median number of the numbers 1 0 4 1 1 4?
You are right. 1 is the median.The median of a set of data is found by arranging the data in increasing or decreasing order. So, we can arrange the items: 0, 1, 1, 1, 4, 4If the number of items of data is even, as it is in this case, then the median is the average (or mean) of the two middle numbers. So, the median is (1 + 1)/2 = 2/2 = 1If the number of items of data is odd, then the median is the middle number in the ordered set. For example the median of the data 1, 3, 3, 5, 6, 8, 9 is 5, because 5 is in the middle.It is also the mode. The mode of a set of data is the one item of data that occurs most often. 1 has the highest number of frequency in this sample. Thus 1 is the mode also.
How do you find the median if the amount of data is even?
If the number of data is even, the median can be found by listing all the data from least to greatest (or from greatest to least, it doesn't matter), crossing out one per side until you are left with two data, and then averaging the two data. For example: 1 2 3 4 5 6 First you cross out 1 and 6, then 2 and 5, so you are left with the middle two, 2 and 3. You average them by adding them together and then dividing by 2. 3 + 2 = 5 5/2 = 2.5 The median is 2.5.
What is the data set with a median of 4?
S={1,2,4,5,7}, the median is 4
What is median in the set of data?
The median in a set of data, would be the middle item of the data string... such as: 1,2,3,4,5,6,7 the Median of this set of data would be: 4
What is the median of 2 3 4 5 7 9?
When there is an even number of data items the median is the mean average of the middle two. → median of {2, 3, 4, 5, 7, 9} = (4 + 5)/2 = 9/2 = 4.5
What is this median of this set of data 12 4 7 16 4 3 8 9 18?
8
Can a data set have the same range and median?
Yes, but the two are measures of very different things. The median is a measure of central tendency whereas the range is a measure of spread. Nevertheless, the set 1, 2, 3, 4, 4 has a range of 3 and a median of 3.
How do you find the median of 4 numbers with 2 of those numbers being the same?
The fact that two of the four numbers are identical in no way changes the way you would find the median. When finding the median of a set of data, you must sort the data from highest to lowest (or lowest to highest). The data point right smack in the middle is the median. If there is an even number of data points -- as is the case here -- you must take the average of the two points in the middle. Let's say these are your data: 10, 10, 6, 3. The median is the average of 10 and 6, or 8. If your data is 10, 6, 6, 3, then the median is 6. If it's 10, 6, 3, 3, the median is 4.5 (the average of 6 and 3).
What is the median and mean1 1 2 2 2 3 3 3 3 4 4 4 5 5 6 7?
The data {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7} has: Median: Thee are 16 data items, so the median is the mean average of the middle two, ie the 8th and 9th numbers: median is (3 + 3) / 2 = 3 Mean: (1 + 1 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 4 + 4 + 4 + 5 + 5 + 6 + 7) ÷ 16 = 55 ÷ 16 = 37/16 = 3.4375
How are mean and median alike?
The mean of a set of data is all the values in that data added together and then divided by the number of values. For instance, if you had the data set 1, 3, 4, 6, 8, you would add them all up to get 22, and then divide by 5 to get 4.4 which is the mean. The median is the middle value of all data values. In the above data set, that is 4, and so 4 would be the median. Mean and median are alike in that they both attempt to find the "middle" of the data, and are both considered averages.
What is the median of 7-3-4?
The median is 4
What is the value that falls in the middle position when the data is arranged in order from smallest to largest?
That's the median. (It is also the 50th percentile.) Exactly half the data lie above the median and half lie below it.For example, consider the following list of numbers: 4, 2, 6, 7, 3, 8, 9.Arranging the numbers from least to greatest, we get: 2, 3, 4, 6, 7, 8, 9.The number 6 is in the middle, so 6 is the median of the data set. If the number of data points is even and no one number is in the center, you must find the average of the two data points in the middle of the list to determine the median.
What happens to the mean median and mode for the data shown if the outlier is eliminated 8 3 5 3 23 4 7?
The mean and median become smaller, the mode does not change.
Can the median answer be a decimals like 5.5?
Yes.Two ways:the data contains non-integer items, eg the median of {1, 1.3, 1.567, 2.4, 5} is 1.567;the data contains an even number of data items. In this case, the median is the mean average of the middle two, which may not be an integer, eg the median of {1, 2, 3, 4} is the mean average of {2, 3} = (2+3)/2 = 2.5
