Question | Answer |
line graph | A graph used to show how a set of data changes over a period of time |
average | the sum of two or more quantities divided by the number of quantities; the mean |
bar graph | A graph using bars to compare quantities. The height or length of each bar represents a designated number |
frequency | The number of items an item occurs |
graph | A visual way to display data |
horizontal axis | The axis on which the categories or values are shown in a bar and line graph |
integers | The whole numbers and their opposites...,-3, -2, -1, 0,1,2,3 |
key | A sample data point used to explain the stems and leaves in a stem and leaf plot. |
line plot | a diagram that shows the frequency of data on a number line |
mean | The sum of the numbers in a set of data divided by the number of pieces |
measures of central tendency | numbers that are used to describe the center of data. These measures include the mean, median, and mode. |
median | The middle number in a set of data when the data are arranged in numerical order. If the data has an even number, the median is the mean of the two middle numbers |
mode | The numbers or items that appear most often in a set of data |
negative numbers | A number that is less than zero |
opposites | Numbers that are the same distance from zero in opposite directions |
outlier | A value that is much higher or much lower than the other values in a set of data. |
positive numbers | A number that is greater than zero |
range | The difference between the greatest number and the least number in a set of data. |
stem-and-leaf plot | A system used to condense a set of data where the greatest place value of the data forms the stem and the next greatest place value forms the leaves. |
vertical axis | The axis on which the scale and interval are shown in a bar or line graph. |
