Why is it a good idea to make a scatter diagram before figuring the correlation coefficient?
Creating a scatter diagram before calculating the correlation coefficient is beneficial because it visually represents the relationship between the two variables, allowing for an easy identification of patterns, trends, or outliers. This preliminary step can help determine whether a linear correlation is appropriate or if the relationship is non-linear. Additionally, it provides context to the numerical correlation coefficient, enhancing the understanding of the data's behavior. Overall, visualizing the data first can lead to more accurate interpretations and informed analyses.

What is the significance of using coefficient of correlation as a statistical tool of analysis?
It tells you how strong and what type of correlations two random variables or data values have. The coefficient is between -1 and 1. The value of 0 means no correlation, while -1 is a strong negative correlation and 1 is a strong positive correlation. Often a scatter plot is used to visualize this.
How scatter diagram helpful in study of correlation?
A scatter diagram, or scatter plot, visually represents the relationship between two variables, making it easier to identify patterns, trends, and correlations. By plotting data points on a Cartesian plane, it allows researchers to quickly assess whether a positive, negative, or no correlation exists between the variables. This visual representation aids in understanding the strength and direction of the relationship, facilitating further statistical analysis. Additionally, it can help identify outliers that may influence the correlation.

What correlation is a scatter graph?
A scatter graph visually represents the correlation between two variables by displaying data points on a Cartesian plane. If the points trend upwards from left to right, it indicates a positive correlation; if they trend downwards, it shows a negative correlation. A scatter graph can also reveal no correlation if the points are scattered randomly without a discernible pattern. The strength and direction of the correlation can be assessed by the density and alignment of the points.
How is a scatter plot that shows no correlation different than a scatter plot that shows a negative correlation?
A scatter plot that shows no correlation displays points that are randomly distributed without any discernible pattern, indicating that there is no relationship between the two variables. In contrast, a scatter plot that shows a negative correlation features points that trend downward from left to right, suggesting that as one variable increases, the other tends to decrease. The absence of a clear trend in a no-correlation plot contrasts with the consistent directional relationship observed in a negative correlation plot.

What are the three ways to describe data in a scatter plot?
You can describe if there's any obvious correlation (like a positive or negative correlation), apparent outliers, and the corrlation coefficient, which is the "r" on your calculator when you do a regression model. The closer "r" is to either -1 or 1, the stronger that correlation is.

a scatter diagram is a tool for analysing relationships.
What does it means to have a correlation in a scatter plot?
A correlation exists in a scatter plot if there is a general trend in the outputs as inputs increase. If the outputs generally increase in value, then there is a positive correlation. If the outputs generally decrease in value, then there is a negative correlation.

Which item below shows bad corranation?
It seems there might be a typo in your question. If you meant to ask about "bad correlation," please provide the specific items or data points you are referring to. Generally, bad correlation occurs when two variables do not show a consistent relationship, often indicated by a low correlation coefficient or a scatter plot that does not display a discernible pattern.
