What is the best fit line in a scatter plot?
A line of best fit is a straight line drawn through the maximum number of points on a scatter plot balancing about an equal number of points above and below the line. It is used to study the nature of relation between two variables.
Which graph shows the best line of best fit for the scatter plot?

What graph has a best fit line?
The Line of Best Fit is used to express a relationship in a scatter plot of different data points.
Do scatter graphs have a line of best fit?
A line of best fit can only be drawn if there is strong positive or negative correlation. The line of best fit does not have to go through the origin. The line of best fit shows the trend, but it is only approximate and any readings taken from it will be estimations.
How do you explain a trend line?
A trendline is a line drawn over pivot highs or under pivot lows to show the prevailing direction of price. Trendlines are a visual representation of support and resistance in any time frame. They show direction and speed of price, and also describe patterns during periods of price contraction. You may also read,
Is line of best fit always straight?
A line of best fit may be a straight line or a curve depending on how the points are arranged on the Scatter Graph. Check the answer of
What does the line in a scatter plot mean?
A scatterplot displays a relationship between two sets of data. … The closer the data points come to forming a straight line when plotted, the higher the correlation between the two variables, or the stronger the relationship.
How do you interpret a regression line from a scatter plot?
If one point of a scatter diagram is farther from the regression line than some other point, then the scatter diagram has at least one outlier. If two or more points are the same farthest distance from the regression line (not a common occurrence), then each of these points is an outlier. Read:
How do you explain a line of best fit?
A line of best fit can be roughly determined using an eyeball method by drawing a straight line on a scatter plot so that the number of points above the line and below the line is about equal (and the line passes through as many points as possible).
How do you know if a line of best fit is good?
The closer these correlation values are to 1 (or to –1), the better a fit our regression equation is to the data values. If the correlation value (being the “r” value that our calculators spit out) is between 0.8 and 1, or else between –1 and –0.8, then the match is judged to be pretty good.
How do you explain a scatter plot?
A scatter plot (aka scatter chart, scatter graph) uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.
What are the 3 types of scatter plots?
Graphs can either have positive correlation, negative correlation or no correlation.
What does a scatter plot show?
A scatterplot shows the relationship between two quantitative variables measured for the same individuals. The values of one variable appear on the horizontal axis, and the values of the other variable appear on the vertical axis. Each individual in the data appears as a point on the graph.
