These are the two most accurate (generally) measures of center for a set of data.
What are mean and median?
100
This is how I calculate the mean for a set of data.
What is add them all up and divide by how many there are?
100
This is how I find the median of a set of data.
What is put them in order from least to greatest and find the middle?
100
This is the measure of variability that I would use when the mean is my center.
What is the mean absolute deviation?
100
These are the three measures of center for data.
What are mean, median, and mode?
200
This is how adding a very high outlier to a set of data will affect the mean, the median, and the mode.
What is the mean will go up by a lot, the median will go up by a little, and the mode will probably not change.
200
The mean can be greatly affected by this kind of data point.
What is an outlier?
200
This is how I find the quartiles of a set of data after I've found the median.
What is find the median of the lower half for the first quartile, then find the median of the upper half for the third quartile.
200
This is the measure of variability that I would use if the median was my center.
What is the IQR?
200
These are the two measures of variability for data, that tell us how spread out the data is.
What are the Mean Absolute Deviation and the IQR?
300
When the median and the mode are not close to each other, there is probably one of these in the data set.
What is an outlier?
300
This is the mean for the following data set:
9, 9, 11, 7, 19, 5, 10
What is 10?
300
This is a very important first step for me to do before I can find the median or quartiles.
What is put the data in order from least to greatest.
300
This is how I calculate the mean absolute deviation.
What is find the mean, make a list of how far each data point is from the mean, and find the mean (average) of those distances.
300
This is the distance between the minimum and the maximum in a data set.
What is the range?
400
Once I've identified a center of data, these are some other things I can use to describe the data from a dot plot.
What is shape/symmetry, gaps, clusters, minimum, maximum, and range.
400
Once I've found the mean, this is how I identify the absolute deviation for a given number.
What is say how far away it is from the mean?
400
This is how I identify the median from a box plot.
What is find the middle line in the box?
400
This is how I calculate the IQR for a set of data.
What is find the first and third quartiles, then subtract to find how far apart they are.
400
This is what I call a question where I expect to get several different answers.
What is a statistical question?
500
This is the thing that my dot plot and box plot are both drawn on top of, that keeps my data organized.
What is a number line?
500
When the set of data is fairly symmetrical and does not have many outliers, this is the measure of center and the measure of variability that will be the most accurate.
What is the mean and the mean absolute deviation?
500
This is the median of the following data set:
13, 16, 14, 13, 11, 16, 15
What is 14?
500
This is what a measure of variability is describing.
What is how far the data is spread out?
500
This is what I call a table that records how often a data point occurs (where the mode is the highest number on the table.
