Q. Find the slope of the median-median line for the dataset in this table.\begin{tabular}{|c|c|}\hlinex & y \\\hline 24.9 & 38 \\\hline 7.2 & 40 \\\hline 15.1 & 25 \\\hline 19.8 & 35 \\\hline 10.3 & 21 \\\hline 2.7 & 26 \\\hline 21.3 & 46 \\\hline 14.7 & 24 \\\hline 17.6 & 44 \\\hline 14.9 & 21 \\\hline 4.4 & 36 \\\hline 7.4 & 22 \\\hline 11.6 & 20 \\\hline\end{tabular}
Sort Data: Sort the dataset by the x-values to make it easier to divide the data into three equal groups.
Divide into Groups: Divide the dataset into three groups with an equal number of points in each group. If the number of data points is not divisible by 3, the middle group may have one more data point than the other two.
Find Median Points: Find the median x-value and median y-value for each group. These points are called the "median points."
Calculate Slope: Use the median points to calculate the slope of the median-median line. The slope m is given by the formula m=x2−x1y2−y1, where (x1,y1) and (x2,y2) are the median points from the first and third groups, respectively.
Calculate Group 1 Median: Calculate the median x-value and median y-value for the first group.
Calculate Group 3 Median: Calculate the median x-value and median y-value for the third group.
Substitute into Formula: Substitute the median points into the slope formula to find the slope of the median-median line.
Find Slope: Perform the calculation to find the slope.
Verify Calculation: Verify the calculation for any mathematical errors.
Report Final Answer: Report the final answer for the slope of the median-median line.
