What is the level of measurement for the mean math scores of students who take math in the morning compared to those who take math in the afternoon?
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.
What is the pattern of a variability within a data set called?
The range, inter-quartile range (IQR), mean absolute deviation [from the mean], variance and standard deviation are some of the many measures of variability.
What does rainfall variability mean?
rainfall variabilty
Does variability include mean median mode and range?
No, it does not
Which measure of variability is used most often in conjunction with the mean?
range
What does the standard deviation of a set of data tell you?
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!
What is climate variability?
