LEVEL 1
Divides the whole distribution into four equal parts.
quartile
It is the measure of variability is obtained by getting the difference between the highest and the lowest scores
Range
It is the most widely used measure of dispersion or variability since it takes into account every value in the set of data.
Standard Deviation
it is the simplest measure of variability.
Range
It is the same as the median of the whole distribution.
second quartile, fifth quartile, 50th percentile
It is defined as the average distance between each value and the mean.
Mean Absolute Deviation
The set of data that is clustered together indicates that it is _________.
homogenous
the square root of the variance
standard deviation
Formula in calculating decile of the ungrouped data
Di=i/10 (n+1)
If the highest score is 37 and the lowest score is 19. What is the range?
18
A class recorded test scores of 49, 67, 72, 81, and 98. What is the range of the scores?
49
it is the average of the squares of deviations from the mean.
variance
What is the first step in calculating quartile, decile and percentile for ungrouped data?
arrange the numbers from either in increasing o decreasing
mean absolute deviation is also called as _______.
average absolute deviation
If the variance is 169, what is the standard deviation?
13
It means how a set of scores are spread out.
variability
What measure of position is usually used to report scores in a test?
percentiles
in the given scores, what is the fifth decile?
5, 2, 10, 3, 9, 19, 18, 11, 8, 10, 14, 3
9.5
The standard deviation is large and the values of set of data are spread apart and it is ____________.
heterogenous
the median of the lower half of the set of data.
first quartile
