Question | Answer |
bar graph | a way of displaying categorical data by using either horizontal or vertical bars on a graph. The height or length of each bar indicates the value for that category. |
categorical data | Data for which each piece of data fits into exactly one of several different groups, also called "qualitative" data. |
circle graph | A graph that shows how parts of the whole relate to the whole, and how parts of the whole relate to other parts. |
Clusters | Areas of the graph where data are grouped close together. |
continuous data | When quantitative data are a measurement of something and can have values that are between two counting numbers. |
Data | the facts or numbers that describe the results of an experiment or survey |
data analysis | Asking statistical questions and collecting, organizing, and analyzing data |
discrete data | When quantitative data are a count of how many, can only have values that are counting numbers (0, 1, 2, 3,...). |
distribution | The overall shape of a graph. |
dot plot | (sometimes called a line plot) is a graph that shows how the discrete data is graphed using a number line. |
double bar graph | is used when each category contains two different data sets. |
Experiment | Whenever you have a question and you collect the data to answer it by performing a test for which you decide the conditions. |
Frequency | The number of times an item or number occurs in a data set. |
frequency table | A table used to organize data according to how many times a data value occurs. |
Gaps | areas of the graph where there are no data |
Histogram | A graphical way to display quantitative or numerical data using vertical bars. The width of a bar represents an interval of data and is often referred to as a bin. |
Key | explains how each data set is represented by a color or a pattern in the graph. |
Parameter | A characteristic of a population. |
Population | An entire set of items from which data can be collected. |
quantitative data | data for which each piece of data can be placed on a numerical scale, also called "numerical" data. |
Sample | a selection from a population. |
skewed left | The peak of the data is to the right side of the graph. There are only a few data points to the left side of the graph. |
skewed right | The peak of the data is to the left side of the graph. There are only a few data points to the right side of the graph. |
stacked bar graph | A graph that stacks the frequencies of two different groups for a given category on top of one another so that you can compare the parts to the whole. |
Statistic | A characteristic of a sample. |
statistical question | a question about a population or a sample. |
Survey | A method for collecting information by asking statistical questions. |
Symmetric | The left and right halves of the graph are mirror images of each other. There is often a "peak" in the middle of the graph indicating there are many data values in the center of the graph. |
side-by-side stem-and-leaf plot | A graph that allows a comparison of the two data sets in two columns. |
stem-and-leaf plot | A graphical method used to represent ordered numerical data. |
