What graphs are used in finding trends in data?
Scatter graphs are best. Line graphs are OK if the trend is linear but not much good if the trend is non-linear.
What is the name of the method for drawing a trend line for the data in a scatterplot?
There are many methods, though the most popular is the method of least squares. This method minimises the sum of the squares of the vertical distances between each point and the corresponding point on the line.
What shows a correlation which may be positive or negative between two sets of data?
I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.
What is a slope on a graph?
The line on the graph that shows what the data is saying.
How does finding the IQR hep you identify the variability of set of data?
The IQR gives the range of the middle half of the data and, in that respect, it is a measure of the variability of the data.
What is the slope of a trend line that passes through the points (1 3) and (10 25)?
Jeremy surveyed students in his class about their spending habits in the school cafeteria. He used the data to create a scatterplot. How Students Spend Money in the Cafeteria Which is the equation of his trend line?
What is a graph that shows the relationships between two sets of data?

Why is determination of density by the slope method generally more accurate than a from individual data points?
The determination of density by the slope method is generally more accurate because it involves finding the slope of a linear relationship between mass and volume, which reduces the effect of random errors in individual data points. This method is based on multiple data points and takes into account the overall trend in the data, leading to a more precise calculation of density.
How can one determine the uncertainty of the slope when finding the regression line for a set of data points?
To determine the uncertainty of the slope when finding the regression line for a set of data points, you can calculate the standard error of the slope. This involves using statistical methods to estimate how much the slope of the regression line may vary if the data were collected again. The standard error of the slope provides a measure of the uncertainty or variability in the slope estimate.
What is a trend on a graph?
It is the description of a slope of a line which connects from many points you mark to show a way that your graph data may increase or decrease. If it is decreasing, you have a downwards trend. If it is increasing, you have an upwards trend.
What is a graph that has a set of data plotted on a x-y plane as a dot for data points?

What is a way of plotting data to show changes occur in related variables?
A scatterplot.
