|---|---|---|---|---|---|
| average | The sum of a set of numbers divided by how many numbers are in the set. It is also called the mean or arithmetic average.
🗑
|
||||
| bar graph | A graph that organizes a collection of data by using horizontal or vertical bars to display how many times each event or number occurs in the collection.
🗑
|
||||
| box-and-whisker plot | A diagram that uses a box to represent the middle of a set of data and segments to the extremes of both ends.
🗑
|
||||
| cluster | Data that are grouped closely together.
🗑
|
||||
| frequency table | A table for organizing a set of data that shows the number of times each item or number appears. It is also called frequency distribution.
🗑
|
||||
| histogram | A bar graph in which the bars represent equally spaced intervals of numbers.
🗑
|
||||
| interquartile range | The range of the middle half of numbers.
🗑
|
||||
| interval | The difference between successive values on a scale.
🗑
|
||||
| leaf | The second greatest place value of data in a stem-and-leaf plot.
🗑
|
||||
| line graph | A graph that shows trends over intervals of time.
🗑
|
||||
| line plot | A diagram showing the frequency of data over a number line. An x is marked above a number on a number line each time that number occurs in a set of data.
🗑
|
||||
| lower extreme | the least number of a set of data. (abbreviated LE)
🗑
|
||||
| mean | The sum of a set of numbers divided by how many numbers are in the set. It is also called the average or arithmetic average.
🗑
|
||||
| median | The middle number of a group of numbers listed in order. If the data is even, the median is the mean of the two middle numbers.
🗑
|
||||
| mode | The number that occurs most often in a given collection of numbers.
🗑
|
||||
| negative correlation | Data points on a scatter plot whose y-coordinates tend to DECREASE as the x-coordinates increase.
🗑
|
||||
| no correlation | Data points on a scatter plot for which no pattern exists among the x- and y- coordinates.
🗑
|
||||
| outlier | Data that is more than 1.5 times the interquartile range from the quartiles
🗑
|
||||
| positive correlation | Data points on a scatter plot whose y-coordinates tend to INCREASE as the x-coordinates increase.
🗑
|
||||
| quartile | One of four equal parts of data.
🗑
|
||||
| range | The difference between the greatest number and the least number in a set of data.
🗑
|
||||
| scale | The set of all possible values of a given measurement, including the least and the greatest numbers in the set, separated by the intervals used.
🗑
|
||||
| scatter plot | A graph or diagram in which two sets of related data are plotted as ordered pairs on the same graph.
🗑
|
||||
| stem | The greatest place value common to all the data values in a stem-and-leaf plot.
🗑
|
||||
| stem-and-leaf-plot | A method of organizing data in increasing or decreasing order - where the greatest place value of the data forms the stem and the next greatest place value forms the leaves.
🗑
|
||||
| upper extreme | The greatest number in a set of data. (abbreviated UE)
🗑
|
||||
| upper quartile | The median of the upper half of a set of data.
🗑
