Scatterplots and correlation review (article) | Khan Academy (2024)

A scatterplot is a type of data display that shows the relationship between two numerical variables. Each member of the dataset gets plotted as a point whose x-y coordinates relates to its values for the two variables.

    Would a V shaped scatter plot have positive correlation, negative correlation, or no correlation?

      If a V shaped scatter plot is perfectly symmetric, there would be no (linear) correlation. So if a V shaped scatter plot is nearly symmetric, there is expected to be little or no (linear) correlation.

  • If you had an "O" shape, would it have a positive, negative, or no linear relationship?

    if you had an X shape as the scatter plot would that have a negative, positive or no correlation

      It is unlikely that there wouldn't be any correlation at all, but it would be very weak for sure, so the correlation coefficient would tend towards zero, and thereby the slope of the regression line would also be close to zero.

      A straight vertical line scatter plot would indicate a perfect negative or positive correlation, depending on the direction of the line. If all the points fall exactly on a straight vertical line from top to bottom, it suggests a perfect negative correlation, meaning that as one variable increases, the other decreases linearly. Similarly, if all the points fall on a straight vertical line from bottom to top, it suggests a perfect positive correlation, indicating that as one variable increases, the other increases linearly.

      Not linear is when there has no tendency to be 'up a ravine or down a ravine'

      Then it would have no linear correlation, and should be marked as having no correlation/no linear correlation.

    why does the no association plots always have to be in a cluster to be identified as no association plots?

      2 months agoPosted 2 months ago. Direct link to daniella's post “The term "no association"...”

      The term "no association" in the context of scatterplots refers to the absence of a clear pattern or relationship between the two variables being plotted. While scatterplots with no association may sometimes exhibit clustering of data points, especially if there's random variation or noise present in the data, this is not a requirement. Scatterplots with no association can have data points scattered across the plot with no discernible pattern or trend. However, it's essential to examine the overall distribution of points to determine whether there's any systematic relationship between the variables or if they're randomly distributed. If there's no apparent relationship, it's classified as having no association.

    Mary is making a scatter plot from two data sets. One set of data gives the amount of precipitation in inches. The second data set is the number of umbrellas sold. Which type of correlation would you expect?

      Making the precipitation the "x-values" and the number of umbrellas sold the "y-values", I would say that the scatter plot would have a positive correlation; people should generally buy more umbrellas as the amount of rain increases.

      Hope this helps!😄

      So, you will most likely have a graph or a table that tells you what you plot on your scatter graph/ scatterplot. For example, you have the height and weight of a student named Emmy, like you! Let's say (may this not be offensive in any way) that you are 140 cm tall (for height) and 45 kg (for weight). Maybe we can put the height on the y axis and the weight on the x axis. Find 45 on the x axis and go up until you reach the same line as 140 on the y axis. This is how you make and use a scatterplot/ scatter graph. Hope I helped you!
