3rd Grade Unit Two
|Bar Graph|| |
a graph that uses the height, or length of rectangles to compare data.
a collection of things sharing a common attribute
examine and note the similarities or differences between two or more objects, problems, numbers, etc...
|Centimeter||a metric unit of length equal to .01 (1/100), one one-hundredth of a meter. 100 of these in a meter|
|certain event|| |
Something that will definitely happen. An event that has a probability of 1. If you have a bag filled with green marbles, picking a green marble will definitely happen.
information, especially numerical information
|Double Bar Graph|| |
in a double bar graph, there are two sets of data or two bars for each item
size of the gap or space between two places
|equally Likely|| |
Having the same chance or probability. 4 white marbles and 4 blue marbles in a bag creates the same chance of drawing a blue or white marble.
|equivalent units|| |
comparing the value of two more unit measurements to find equal values. 100 centimeters = 1 meter
customary unit of length equal to 12 inches (ft)
|Feet||plural of foot, more than one foot. (ft)|
a drawing that shows a relationship between sets of data.
a graph that uses pictures to show and compare information
The distance between two numbers on the scale of a graph
|impossible event|| |
an event with a probabilty of zero (0). An event that cannot happen. If you have a bag filled with green and blue marbles, there is zero probability that you will draw a red marble.
a customary unit of length equal to 1/12 of a foot. There are 12 of these in one foot.
|graph key|| |
a list which explains the symbols on a graph
For example: $=100 dollars $$= 200 dollars
one dimension of a 2-or 3-dimensional figure
|line plot|| a graph showing frequency of data on a number line|
X X X
X X X X X
|mode||the number that appears most frequently in a set of numbers. There may be one, more than one, or no mode.|
|median||The middle number when numbers are arranged from least to greatest. The median of 3, 4, 7, 9 and 10 is 7. When the set has two middle numbers, the median is the mean of the two middle numbers.|
|metric system||a system of measurement based on tens. The basic unit of length is the meter. The basic unit of mass is the gram. The basic unit of capacity is the liter.|
|measure||a comparison to some other known unit, or to find the measure of something|
|outlier||Any data point that sticks out. NOT all data sets have one.|
|outcome||one of the possible things that can happen in a probability experiment or problem.|
|possible||something that can be done, something that can happen|
|probability||the chance of an event happening.|
|range||the difference between the greatest number and the least number in a set of numbers (data). The range of the numbers 5,9,8,2,and 6 is 7 9-2=7|
|record||make a record of, to write down, type up, save as an audio fil-e|
an instrument used for weighting
|scale (on a map)|| |
a statement or diagram that tells the actual distance represented by a distance on a map. For example: 1 inch on the map = 100 miles on the road
|scale (on a graph)|| |
the numbers along the axes of the graph.
|sample space||A list of all of the outcomes|
|survey||the process of asking a group of people the same question. For example: Do you like ice cream?|
an organized way to list data. Tables usually have rows and columns of data.
|tally marks|| |
marks made to keep track of things being counted.
|U.S. customary system|| |
a system of measurement used in the U.S. The system includes units for measuring length, capacity, weight, and temperature. Feet, ounces, and gallons are examples of customary units of measurement.
a customary unit of length equal to 3 feet.
