Plot a linear model for the given data: Given data represents the values of Earth’s atmosphere for the years 1950 to 1985. EXCEL software can be used to compute a linear model for the given data. Software Procedure: The step-by-step procedure to plot a linear model using EXCEL software is given below: Open an EXCEL file. Enter the data of Years in column A and name it as Years. Enter the data of Atmosphere in column B and name it as Atmosphere. Select Data and go to Insert tab. Select Scatter or Bubble chart > Scatter plot. Click OK. Select any point on the Scatterplot and left click on it. Select add trendline. Select Linear and click on display equation and R2. The Scatterplot with linear equation is shown below: Plot a quadratic model for the given data: EXCEL software can be used to compute a quadratic model for the given data. Software Procedure: The step-by-step procedure to plot a quadratic model using EXCEL software is given below: Open an EXCEL file. Enter the data of Years in column A and name it as Years. Enter the data of Atmosphere in column B and name it as Atmosphere. Select Data and go to Insert tab. Select Scatter or Bubble chart > Scatter plot. Click OK. Select any point on the Scatterplot and left click on it. Select add trendline. Select Polynomial > order - 2 and click on display equation and R2. The Scatterplot with quadratic equation is shown below:Plot an exponential model for the given data: EXCEL software can be used to compute an exponential model for the given data. Software Procedure: The step-by-step procedure to plot an exponential model using EXCEL software is given below: Open an EXCEL file. Enter the data of Years in column A and name it as Years. Enter the data of Atmosphere in column B and name it as Atmosphere. Select Data and go to Insert tab. Select Scatter or Bubble chart > Scatter plot. Click OK. Select any point on the Scatterplot and left click on it. Select add trendline. Select Exponential and click on display equation and R2. The Scatterplot with exponential equation is shown below: Plot a power model for the given data: EXCEL software can be used to compute a power model for the given data. Software Procedure: The step-by-step procedure to plot a power model using EXCEL software is given below: Open an EXCEL file. Enter the data of Years in column A and name it as Years. Enter the data of Atmosphere in column B and name it as Atmosphere. Select Data and go to Insert tab. Select Scatter or Bubble chart > Scatter plot. Click OK. Select any point on the Scatterplot and left click on it. Select add trendline. Select Power and click on display equation and R2. The Scatterplot with power equation is shown below: Among all the four R2 values, (0.9648, 0.9984, 0.9697 and 0.8095), the highest R2 value is 0.9984. Since, the coefficient of determination is highest for the quadratic model, quadratic model is the best fit for the given data. The percentage of variation in the values of earth’s atmosphere, explained by the variation in the values of year and the regression model is 99.84%. The global mean temperature in 2015 is predicted as given below: The best model Quadratic model and the predicted value of the mean temperature is 412.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
