It gives a measure of the spread of the data.you
What else can I help you with?
Why was Sandy's choice of a line graph a good one for this set of data?
It's impossible to tell unless we have both the graph and the set of data.
What does the median of a set of data tell you?
The median is the midpoint of the data set. So half the observations are greater than the median and half are smaller.
What does range tell you about the data set?
Range tells you the interval in which the f(x) values are found.
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 does the Interquartile range tell you about the data set?
It tells you that middle half the observations lie within the IQR.
What a small MAD tell you about a data set?
It means that there is little variability in the data set.
What is the mean in Mad of this data set?
How should I know?
What does the median tell you about the distribution of a set of data?
the midpoint of the data set
What is the mean absolute deviation of the data set shown?
To calculate the mean absolute deviation (MAD) of a data set, first find the mean of the data. Then, subtract the mean from each data point to find the absolute deviations. Finally, take the average of these absolute deviations. If you provide the specific data set, I can help calculate the MAD for you.
What must you know about a data set before you can use the empirical rule?
The data set must be unbiased, the outcomes of the trials leading to the data set must be independent. The data set must be large enough to allow the Law of Large Numbers to be effective.
What does the IQR tell you about a data set?
It gives a measure of the spread of the data.
When a large set of data is gropued it is known as?
A Population
What is the average from a large set of data called?
The mean!
What does the mean tell you about a set of data?
The mean tells the sum of the whole set of data.h
What does the mean adsolute deviation tell you about a data set?
it tells you
Tell when a set of data can have no mode?
A set of data has no mode when there is no number that occurs more frequently than another. The data set: 1, 2, 5, 5, 6 has a mode of 5. The data set: 1, 2, 3 has no mode.
Why was Sandy's choice of a line graph a good one for this set of data?
It's impossible to tell unless we have both the graph and the set of data.
