Which of the following measures tells something about the distribution of a data set?
answers mean median range
mean right
Mean, and median are both measures of central tendency, so they won't tell you a whole lot about the distribution of the data set.
ok
In other words, they tell you where the "middle" of the data set is, where distribution is about where ALL the data is.
ok so what should i put
The one that isn't a measure of central tendency.
The mean just gives the average. For data set: { 4,5,6} and {1,5,9}. Both gives the same mean of 5 so we can tell clearly that mean doesnt say much about the distribution. Mean is obviously not the answer we are looking for. Next, is median. For data set: { 4,5,6} and {1,5,100} Both have the median 5. Looking at the vast difference between the 2 data sets, you can tell also that median cannot actually tell you the distribution of the data set. Next Range, For data set: {4,5,6} and {1,5,100} The ranges will be [4,6] and [1,100] The range definitely tell you the distribution of the 2 data sets not matter how big a difference the 2 data sets may have.
what one then
Don't just go hunting for the answers. Me and dalvoran gave you very clear explanations. Try reading them and understand?
ok
