The sum of the squares of the deviations (how far each point is from the line) is less, for such a line, than for any other line.
It is sometimes true that a scatter plot showing a positive association suggests a proportional relationship, but not always. A positive association indicates that as one variable increases, the other tends to increase as well, but the relationship may not be linear or proportional. Proportional relationships require that the ratio of the two variables remains constant, which is not guaranteed by a positive association alone. Therefore, while some positively associated relationships can be proportional, others may not be.
True
No. It uses continuous data. * * * * * Not true. It can use either discrete or continuous data.
The answer depends on the purpose of the plot.
The outlier is the number in a line plot that is right after the gap, the number that is way far away from all the clusters but sstill has data recorded in it, basically its just the odd one out of the bunch, almost like it doesnt belong or make sense but is true.
Yes if all points are on the same line of best fit
Based on the information given in the question, nothing particularly is true. The line need not be straight, or even a smooth curve. There need not be any points on the line but there need not be any points not on it.
True. In a data plot, the line of best fit represents the average trend of the data. Therefore, approximately half of the data points should lie below the line of best fit and half should lie above it if the data is evenly distributed.
