What is a trend line on a scatter plot?
A. a visual representation of the relationship between two variables.
B. a line connecting only the highest and lowest values on a graph.
C. A line connecting all the data points on a scatter plot*
D. Any line of data on a graph
It was A.
Yes. A
Lol thanks
The correct answer is A. A trend line on a scatter plot is a visual representation of the relationship between two variables. It helps to show the general direction or pattern of the data points in the scatter plot.
To understand what a trend line represents, you will first need to plot a scatter plot using the given data points. A scatter plot is a graph that displays individual data points as dots on a Cartesian coordinate plane, with one variable represented on the x-axis and the other variable represented on the y-axis.
Once you have plotted the data points on the scatter plot, you can now determine the trend line. The trend line is a line that is fitted to the data points in a way that best represents the overall relationship between the variables. It helps to identify any patterns, trends, or correlations in the data set.
There are different methods to calculate and draw a trend line, such as least squares regression or moving averages. These methods aim to minimize the distance between the trend line and the individual data points, providing the best approximation of the relationship between the variables.
A trend line is not simply a line connecting the highest and lowest values on the graph (option B). It is also not just any line of data on a graph (option D). Instead, it is specifically a line that represents the overall relationship between the variables in a scatter plot (option A). Option C, "A line connecting all the data points on a scatter plot," is not the accurate definition of a trend line as well, as a trend line may not necessarily pass through all the data points, but rather captures the general direction or pattern.
