What type of data is best for scatter plots?
A scatter chart works best when comparing large numbers of data points without regard to time. This is a very powerful type of chart and good when your are trying to show the relationship between two variables (x and y axis), for example a person’s weight and height.
What is a scatter plot best used to effectively display?
A scatter plot or scattergram chart will show the relationship between two different variables or it can reveal the distribution trends. It should be used when there are many different data points, and you want to highlight similarities in the data set.
What is a scatter plot for what type of data is scatter plot usually used for?
Scatter plots are used to plot data points on a horizontal and a vertical axis in the attempt to show how much one variable is affected by another.
What do scatter plots show?
A scatterplot shows the relationship between two quantitative variables measured for the same individuals. The values of one variable appear on the horizontal axis, and the values of the other variable appear on the vertical axis. Each individual in the data appears as a point on the graph.
Which chart type provides the best visual display of the relationship?
Pie Chart. Pie charts are best used with one string and one numeric variable. They show a part-to-whole relationship (when the total amount is one of your variables and you’d like to show the subdivision of variables).
Why is a scatter plot an appropriate display for this data set?
A scatter plot can also be useful for identifying other patterns in data. We can divide data points into groups based on how closely sets of points cluster together. Scatter plots can also show if there are any unexpected gaps in the data and if there are any outlier points.
How do you describe data on a scatter plot?
Overall Pattern: To describe a scatterplot, state the direction (positive or negative), form (is it linear?), how strong the relationship appears (how large is the scatter), and identify any outliers.
What type of correlation is shown in the scatter plot?
The scatter plot shows a positive correlation.
Which type of data would be best displayed in a histogram?
The histogram is a popular graphing tool. It is used to summarize discrete or continuous data that are measured on an interval scale. It is often used to illustrate the major features of the distribution of the data in a convenient form.
What graph is best use to show classes or groups of data in proportion to the whole data set?
Bar charts are a standard way to graph discrete variables. Each bar represents a distinct value, and the height represents its proportion in the entire sample.
