SCUBA divers have maximum dive times they cannot exceed when going to different depths. This table shows the for certain depths. Depth ( m ) 18 21 24 27 30 33 Time [ min ] 55 45 35 25 22 15 Find the maximum depth and the time at that maximum depth.

A scatter diagram takes the two sets of data and plots one set on the x -axis(horizontal axis) and the other set on the y -axis (vertical axis). Draw a graph with the independent variable on the horizontal axis and the dependent variable on the vertical axis. A scatter plot 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. Here, data values of depth are taken on the x -axis and and its corresponding time values are taken on the y -axis. Scatter diagram of the given data is A general downward trend shows a negative correlation: y decreases as x increases. Here, the maximum depth is 33 m and its corresponding time is 15 min . Thus, as the maximum depth increases the time at that depth decreases.

Here, data values of distance are taken on the x -axis and its corresponding fuel values are taken on the y -axis. Scatter diagram of the given data is A scatter diagram not only shows you whether the correlation between two variables is positive or negative or no correlation, but also tells you something about the strength of the correlation. The stronger the correlation, the more the points will look like a straight line. A general upward trend shows a positive correlation: y increases as x increases. From the above scatter diagram, it is a strong positive correlation. When all the points on the scatter diagram tends to lie near a line which looks like a straight line, the correlation is said to be linear and when all the points on the scatter diagram tend to lie near a smooth curve, the correlation is said to be non-linear. Thus, the correlation is linear, because all the points on the scatter diagram tends to lie near a line which looks like a straight line. Thus, the correlation is strong, positive and linear.
