What type of graph would be best for data points?
A scatter plot would be best for non-related data points. A line graph would be best for related data points.
Is it true that all data points have to be shown?
The answer depends on the purpose of the plot.
What do the x's on a line plot means?
They are the data points, plotted on the appropriate coordinates!
In a data plot about half the data points will lie below the line that best fits?
Yes. The exception arises when you have outliers.
When using the Regression tools you cannot plot the points of your data and your model on the same graph?
False
What is placing dots on all data points?
You can have a scatter plot where the data is displayed as a collection of points. You can also have a dot plot where a set of data is represented by placing dots over a number line to represent the frequency of data.
What type of graph would be best for data points?
A scatter plot would be best for non-related data points. A line graph would be best for related data points.
In data plot most of the data points will lie below the line of best fit?
False
What is shown on a scatter plot when the points show no pattern?
randomness of data
Is it true that all data points have to be shown?
The answer depends on the purpose of the plot.
What are some benefits of recording data on a stem and leaf plot?
There are many benefits of using a stem and leaf plot in the analysis of data. A stem and leaf plot can be constructed quickly. The value of each data point can be recovered from the plot. The data is arranged compactly because the stem is not repeated in multiple data points.
What do the x's on a line plot means?
They are the data points, plotted on the appropriate coordinates!
A line that best fits the data points on a scatter plot?
A straight line which best describes the data on a scatter plot is called a "line of best fit". The line could pass through some of the points, all of them, or none of them.
A line that is very close to most of the data points in a scatter plot?
line of fit
In a data plot about half the data points will lie below the line that best fits?
Yes. The exception arises when you have outliers.
When using the Regression tools you cannot plot the points of your data and your model on the same graph?
False
True or false in a data plot about half the data points will lie below the line of best fit?
True. In a data plot, the line of best fit represents the average trend of the data. Therefore, approximately half of the data points should lie below the line of best fit and half should lie above it if the data is evenly distributed.
