Assignment Help Mechanical Engineering
Reference no: EM132641193

Which two attributes are the most strongly correlated? MPG and Engine_Size Vweight and MPG

  • Vweight and Engine_Size
  • Cylinders and Engine_Size

Which two attributes are the most weakly correlated?

  • Engine_Size and Cylinders
  • Acceleration and Vweight
  • Acceleration and MPG
  • Engine_Size and MPG

What is the relationship between Horse_Power and MPG?

  • As MPG decreases, Horse_Power decreases.
  • As MPG increases, Horse_Power increases.
  • There is no meaningful relationship between Horse_Power and MPG.
  • As Horse_Power increases, MPG decreases.

What is the nature of the statistical relationship between Horse_Power and Acceleration?

  • Of all the attributes Acceleration is correlated to, its relationship with Horse_Power is the weakest.
  • Acceleration is correlated to Horse_Power in a statistically meaningful way, but it is even more strongly correlated to MPG.
  • There is no meaningful statistical relationship between these two variables.
  • There is a relatively strong relationship between these two variables.

What is the weakest correlation coefficient in the data set?

  • -0.830
  • -0.413
  • -0.802
  • 0.408

What is the strongest correlation coefficient in the data set?

  • -0.802
  • -0.830
  • 0.950
  • 0.935

Considering only attributes that have relationships where their values go in opposite directions, what is the strongest correlation coefficient in the data set?

  • -0.830
  • 0.408
  • -0.802
  • 0.950

Are there any attributes in the data set that should be removed because they have no meaningful correlations to any other attributes?

  • Yes. MPG has too many negative correlations to be a meaningful attribute.
  • No. All attributes have multiple correlations that would be considered very strong.
  • Yes. Engine_Size has too much variability for any correlations to be meaningful.
  • No. All attributes have at least one statistically meaningful correlation.

Which of the following is an alternative operator to Correlation Matrix in RapidMiner?

  • Mutual Information Matrix
  • Spearman Correlation
  • Clustering
  • Scatterplot

Assuming you were going to add a new attribute to the data set, which of the following would you expect to have the strongest correlations to the existing attributes?

  • Wind resistance rating
  • Color ID
  • Customer satisfaction rating
  • Country of origin ID
