Can you recommend any concrete strategies that may be used to track the movement of data

An article gave a scatter plot along with the least squares line of x = rainfall volume (m³) and y = runoff volume (m³) for a particular location. The accompanying values were read from the plot. x 5 12 14 19 23 19 23 30 40 52 55 67 72 82 96 112 127 y 4 10 13 14 13 14 15 25 27 44 38 46 53 69 82 99 105 (a) Does a scatter plot of the data support the use of the simple linear regression model? Yes, the scatterplot shows a reasonable linear relationship. O Yes, the scatterplot shows a random scattering with no pattern. O No, the scatterplot shows a reasonable linear relationship. O No, the scatterplot shows a random scattering with no pattern. (b) Calculate point estimates of the slope and intercept of the population regression line. (Round your answers to four decimal places.) slope intercept (c) Calculate a point estimate of the true average runoff volume when rainfall volume is 51. (Round your answer to four decimal places.) m³ 3 (d) Calculate a point estimate of the standard deviation…

What more steps, in addition to these measures, may be taken to ensure the legitimacy of the data that was gathered in the field?

Is it possible to describe the "slice and dice" method that is utilised in multidimensional models?
