Yes.
range,mode ,mean and cluster
If the raw math scores are available for all of the students then you could probably apply a t test to the results. Alternatively you could use a Wilcoxon rank sum test. The difficulty you face is that, without a measure of the variability in the scores you cannot be sure that the difference in the means is due to actual difference or just variability. To get that measure you need th raw scores.
The range, inter-quartile range (IQR), mean absolute deviation [from the mean], variance and standard deviation are some of the many measures of variability.
No, it does not
It looks like there might be a typo in your question. Did you mean "dimension"? In math or science, a dimension refers to a specific aspect or characteristic of an object, such as length, width, or depth in three-dimensional space. It can also represent a measure of freedom or variability in a system.
range
What does length mean in math
It tells you how much variability there is in the data. A small standard deviation (SD) shows that the data are all very close to the mean whereas a large SD indicates a lot of variability around the mean. Of course, the variability, as measured by the SD, can be reduced simply by using a larger measurement scale!
Climate variability is unknown
Lack - verb, does not haveVariability - noun, the quality of change or difference
The answer will depend on what the question actually is!
The usual measures of variability cannot.
