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.
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 is the difference between simple frequency distribution and grouped frequency distribution?
frequency is the kinds of the line graph, bar graph, picture graph, pie graph. that's all
Is a histogram a graph that represents the cumulative frequencies for the classes in a frequency distribution?
No it is not. The ogive is a graph that represents the cumulative frequencies for the classes in a frequency distribution.
How do you find the median of a bar graph?
you cross the bars out from order from left to right.
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.
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.
What is a normal distribution graph called?
It has no special name - other than a normal (or Gaussian) distribution graph.
How do you find graph median by using standard deviation?
You cannot because the median of a distribution is not related to its standard deviation.
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 positively skewed distribution?
A positively skewed or right skewed distribution means that the mean of the data falls to the right of the median. Picturewise, most of the frequency would occur to the left of the graph.
What is unimodel?
Unimodal is having a normal disturbution. The mean, median, and mode are all a the center. When looking at a graph, there is one maximum.
In what graph is the median not important?
A bimodal graph in which the modes are at the extrema.
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.
The graphs below show the distribution of heights among people who live in four different countries. On average which country has the tallest people?
Based on the graphs showing the distribution of heights among people in four different countries, the country with the tallest people can be determined by looking at the graph with the highest peak or median height. The country whose graph shows the highest peak or median height generally has the tallest people on average.
