Descriptive statistics
What are the 3 measures of center we talked about in class
mean median and mode
What is range
It's a single data set numeric value computed by subtracting the minimum of the maximum
What is a line segment
A line segment is a part of a line that has two endpoints and includes all the points between them
What is a polygon
A polygon is a closed, flat shape made of straight line segments.
What is the basic unit of geometry, defined by a flat surface with straight sides that enclose a space.
A polygon
What Is the mean
The mean is the average of a set of numbers. It is found by adding all the numbers together and dividing by how many numbers there are.
Is it true of false that for a given set of numerical data a measure is speed is a number that measures the amount of variability
True
What is a congruent segment
Congruent segments are line segments that have the same length, even if they are in different positions or directions.
What is the name of a 4 sided polygon
Quadrilateral
what is a straight figure that starts at one point and extends endlessly in two directions
A line
what is median
The median is the middle number in a set of numbers when they are put in order from least to greatest
What are the 3 measures of speed that we learned about in class
Standard deviation, range, and interquartile range
What is a collinear
Collinear means that points lie on the same straight line.
What is the name of a 6 sided polygon
Hexagon
what is type of angle measures exactly 90 degrees
90 degrees
what is mode?
The mode is the number that appears the most in a set of numbers.
What is standard deviation sometimes shortens to
STD or STDeV
What is a coplanar
Coplanar means that points or lines lie in the same plane (the same flat surface)
What is the name of a 11 sided polygon
Undercagon
what are Two lines in the same plane that never meet, no matter how far they extend.
What are parallel lines
when we want to describe a numerical datd se using only a single number what do we use
measure of center
What is the 5 number summary for data
What is a ray
A ray is a part of a line that starts at one endpoint and goes on forever in one direction
What is the name of a 67 sided polygon
hexacontakaineptagon or a 67-gon
what is an angle that measures more than 90° but less than 180°
What is an obtuse angle
