Explain why the term bell curve is appropriate for a graph of a normal distribution of traits?
No
What kind of graph would you use to show the scores?
When putting the scores in, you use the normal distribution graph, which is the best start.
What is a bell-shaped distribution in statistics?
It is called a normal distribution.
How can one determine the median from a graph?
The answer depends on what the graph is of: the distribution function or the cumulative distribution function.
Is this correct the graph of a normal distribution is bell-shaped?
Roughly speaking, yes. However, bells do not extend asymptotically to infinity.
How does the median affect the graph of a normal distribution?
A normal distribution is symmetrical; the mean, median and mode are all the same, on the line of symmetry (middle) of the graph.
How does the mean affect the graph of a normal distribution?
It determines the location of the graph: left or right - but not its shape.
Explain why the term bell curve is appropriate for a graph of a normal distribution of traits?
No
The graph of a cumulative frequency distribution is called?
ogive
What kind of graph would you use to show the scores?
When putting the scores in, you use the normal distribution graph, which is the best start.
What is a bar graph representing frequency distribution with no spaces between the bars is called an?
a bar graph
What is a bell-shaped distribution in statistics?
It is called a normal distribution.
What is a normal data set?
A normal data set is a set of observations from a Gaussian distribution, which is also called the Normal distribution.
What are the units on a bar graph called?
the unit on a bar grapg are called unit of uniform distribution.
Describe the properties of a normal distribution?
A normal distribution is symmetric and when looked at on a graph, the graph looks like a bell shaped curve. Approximately 95 percent of its values should lie within two standard deviations of the mean. Frequency of the data lies mostly in the middle of the curve.
What kind of graph is a bell shaped curve?
The bell curve graph is another name for a normal (Gaussian) distribution graph. A Gaussian function is a certain kind of function whose graph results in a bell-shaped curve.
What is the distribution with an means of 0 and a standard deviation of 1?
It is called a standard normal distribution.
