Median Smoothing and Centering Quiz

What is the main challenge when using median smoothing with an even number of points?

• It is only applicable to odd numbers.

• It is impossible to calculate.

• It requires additional steps for centering.

• It results in inaccurate data.

In the four median smoothing process, how is the median point determined for a group of four data points?

• By using only the first and last points.

• By selecting the highest and lowest points.

• By finding the midpoint between the second and third points.

• By averaging all four points.

What is the purpose of the centering step in the median smoothing process?

• To eliminate outliers.

• To refine the median points by finding midpoints between pairs.

• To add more data points.

• To simplify the graph.

During the centering step, how are the new median points determined?

• By averaging all previous median points.

• By finding the midpoint between each pair of median points.

• By selecting the highest previous median point.

• By using the first and last median points only.

What is the final step after determining the centered median points?

• Calculating the average of all points.

• Plotting the original data again.

• Removing all previous data points.

• Joining the centered points with a line.
