South Habersham Middle School 6th Grade Math Powertime Vocabulary Unit 4

Box and Whisker Plot A diagram that summarizes data using the median, the upper and lowers quartiles, and the extreme values (minimum and maximum). They are also known as box plots.
Frequency The number of times an item, number, or event occurs in a set of data
Grouped Frequency Table The organization of raw data in table form with classes and frequencies.
Histogram A way of displaying numeric data using horizontal or vertical bars so that the height or length of the bars indicates frequency.
Inter-Quartile Range (IQR) The difference between the first and third quartiles. (Note that the first quartile and third quartiles are sometimes called upper and lower quartiles.)
Mean Absolute Deviation The average distance of each data value from the mean. It is a gauge of “on average” how different the data values are form the mean value.
Mean The “average” or “fair share” value for the data. It is also the balance point of the corresponding data distribution.
Measures of Center The mean and the median are both ways to measure the center for a set of data.
Measures of Spread The range and the Mean Absolute Deviation are both common ways to measure the spread for a set of data.
Median The value for which half the numbers are larger and half are smaller. If there are two middle numbers, it is the arithmetic mean of the two middle numbers.
Mode The number that occurs the most often in a list. There can be more than one or none.
Outlier A value that is very far away from most of the values in a data set.
Range A measure of spread for a set of data. To find this measure, subtract the smallest value from the largest value in a set of data.
Stem and Leaf Plot A graphical method used to represent ordered numerical data. Once the data are ordered, the stem and leaves are determined. Typically the stem is all but the last digit of each data point and the leaf is that last digit.
