1
is a measure of variability, based on dividing a data set into quartiles.
2
a quantity calculated to indicate the extent of deviation for a group as a whole.
3
the hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.
4
the probability of rejecting the null hypothesis when the null hypothesis is true.
5
a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval
6
a diagram in which the numerical values of variables are represented by the height or length of lines or rectangles of equal width.
7
the probability of obtaining a test statistic result at least as extreme as the one that was actually observed, assuming that the null hypothesis is true.
8
indicates how many standard deviations an element is from the mean
9
the area of variation between upper and lower limits on a particular scale.
10
average of the numbers
