It tells you that if there were a linear relationship between the two variables, what that relationship would look like and also how much the observations differed from that linear fit.
What else can I help you with?
How do you figure out the equation of a table with a graphic calculator?
It depends on which calculator! If the data is linear, you can estimate the slope of the line and the y-intercept from graphing the data. By graphing the data, you will be able to tell if it forms a straight line or not.
What is the difference between a data marker and data label?
On a chart, such as a line chart, a data markers shows where the point is, usually done with a dot or a box or a cross. A data label will show the actual value of that data point. So on a line chart you might see a data marker on the line to indicate it is a value from the data and with it a data label will tell you what the actual value is.
How do you know when to draw a curve or straight line when drawing a line of best fit?
A visual inspection of the scatterplot should tell you whether a straight line or a simple curve is appropriate. You could carry out an analysis of variance (ANOVA) and test the reduction in the residual sums of squares to see whether the curve is significantly better than the line. However, remember that with n observations, a curve with n-1 independent parameters (for example a polynomial of order n-1) will give a prefect fit.
Why was Sandy's choice of a line graph a good one for this set of data?
It's impossible to tell unless we have both the graph and the set of data.
What is display each set of data in a line plot mean?
It means i need help can u tell me what It means
Who can tell me the best auto sales about in California?
The best auto sales in California can be found in local dealerships in California that will tell you about their monthly and annual sales data and let you know what is best.
What does calculating the slope of the graph line tell you about the data?
It tells you if the data raised alot or little.(Ex:if the first point is x95:y5 and the second is x95:y90 it is a steep slope.)
Can you tell just by looking at two line plots which data set has the greater mean?
No. Definitely not if the lines intersected near their means.
If you are given a box plot without any numbers on the number line what can you tell about the data used to make the plot?
You could tell whether or not the data were skewed but that is all. You could make no assessment about the central tendency (mean) or spread (range, inter-quartile range).
How can you tell whether two sets of data vary directly?
The ratio of a pair of values is always the same. or The scatter plot of the data indicates a straight line with a positive slope that passes through the origin.
How would you tell what type of graph you use?
You usually want to use a bar graph. If you have a year of data you probably want to use a line graph.
How can you tell if you have a good telephone service?
Good telephone service is very important. The best way to tell is by the quality of sound on both ends of your line.
