How to draw line of best fit ( Scatterplot)

What is the main purpose of a scatter plot?

• To show how parts make up a whole

• To display data over a period of time

• To show the relationship between two different variables

• To compare different categories of data

What are the three types of correlation that can be determined from a scatter plot?

• Strong, weak, and no correlation

• Positive, negative, and null correlation

• Upward, downward, and flat correlation

• Direct, inverse, and zero correlation

When drawing a line of best fit, what is an important guideline regarding the data points?

• All data points must touch the line

• More data points should be above the line than below

• An equal number of data points should be on both sides of the line

• The line should only connect the first and last data points

What does it mean if a scatter plot shows 'no correlation'?

• The data points form a clear straight line

• The data points are tightly grouped together

• The data points are spread out randomly with no clear pattern

• The data points show a strong upward trend
