Which value is NOT always a number in the data set it represents?
The range, median, mean, variance, standard deviation, absolute deviation, skewness, kurtosis, percentiles, quartiles, inter-quartile range - take your pick. It would have been simpler to ask which value IS in the data set!
Which data set has the greatest spread for the middle 50 of its data?
The data set whose inter-quartile range is the largest.
Explain how to find the range of set of data?
The range = the difference between the highest and the lowest values in the data set. For example if I had a data set like this: 10, 20, 30, 40, 50 50 is the highest number and 10 is the lowest number. 50-10= 40. 40= the range of the above data set.
The range of a set of data is 48 If the lowest value in the data set is 2 what is the highest value?
50
How does the outlier affect the range of a data set?
Range subtracts the lowest value from the value in your data set. If you have an outlier, meaning a number either obviously outside the data, your range will be incorrect because one of the values will not represent the average pattern of the data. For example: if your data values include 1,2,3,4,and 17, 17 would be the outlier. The range would be 16 which is not truly representative of the rest of the data.
Is the mean and median mode and range always part of a data set?
yes it is always * * * * * That is pure rubbish. The mean and median score for a throw of a die are 3.5 But there are not many dice with a face value of 3.5! The mode must be - always. The range often is not. If the height of adult males ranges in height from a minimum of 1.5 metres to a maximum of 2.0 metres, then the range is 0.5 metres. However, the fact that the minimum is 1.5 m implies there is no male with a height of 0.5 m. So, the range is not part of the data set.
Is median always part of the data set?
yes* * * * *No. If you have a small, even number of observations, the median is the average of the two middle values. This will usually NOT be part of the data set.
What is always part of a data set?
An observation.An observation.An observation.An observation.
Which measure of central tendency is always part of any data set?
mean
What is the range of a set data how do you find it?
Range is the biggest number in a set of data subtracted by the smallest number in that set of data.
Calculated by subtracting the smallest value in the data set from the largest value in the data set?
The range is the size of the set of data. Take the smallest from the largest value to get the range
What is a range of data?
When you are presented with a set of data and you need to find the range, you must subtract the lowest number in your data set from the highest number in the data set provided. For example, you are presented with this data set and you must find the range of the data. 34, 82, 43, 13, 14 You have to subtract the lowest number (13) from the highest number (82) so the range of this data set is 69. If you want to find the range you look at your data. Then you find the maximum number and the minimum and you subtract the two. Then you have your range.
What is the range of the data how do you find it?
You subtract the smallest data point from the largest data point in the set. The result is the range.
Which value is NOT always a number in the data set it represents?
The range, median, mean, variance, standard deviation, absolute deviation, skewness, kurtosis, percentiles, quartiles, inter-quartile range - take your pick. It would have been simpler to ask which value IS in the data set!
What is calculated by subtracting the smallest value in the data set from the largest value in the data set?
Range
When you subtract the highest data point from the lowest data point?
When you subtract the highest data point from the lowest data point, you are finding the range of the data set. Range provides a measure of how spread out the values in the data set are.
What is the range of a set of data?
The range is the size of the set of data. Take the smallest from the largest value to get the range.
