Quiz zum Vortrag

  1. We can determine the form of a relationship between two quantitative variables
  2. We can determine the form of a relationship between two categorical variables
  3. We can determine the correlation between two quantitative variables
  4. We can determine the strength of a relationship between two categorical variables
  1. This means that as the values of the X variable increase, the values of the Y variable increase
  2. This means that as the value of the X variable increases, the value of the Y variable decreases
  3. This means that as the value of the X variable decreases, the value of the Y variable increases
  4. This means that the values of X and Y are all positive
  1. Correlation measures the strength of a linear relationship between two categorical variables
  2. Correlation measures the strength of a linear relationship between two quantitative variables
  3. Correlation takes values between -1 and 1
  4. Correlation indicates the direction of a linear relationship between two quantitative variables
  1. Correlation does not have a unit of measurement
  2. Two quantitative variables with correlation 0.6 have a stronger linear relationship than two quantitative variables with correlation -0.6
  3. If two quantitative variables are highly correlated, it can be concluded that changing the value of the explanatory variable causes the change in the response variable
  4. Outliers have little effect on the correlation
  1. Correlation is appropriate when measuring the strength of a relationship between two quantitative variables that appear to be linearly related and have no outliers present
  2. Correlation is appropriate when measuring the strength of the relationship between two categorical variables
  3. Correlation is appropriate when measuring the strength of a relationship between two quantitative variables that appear to be linearly related and have several outliers present
  4. Correlation is appropriate for measuring the strength of the relationship between two quantitative variables when the relationship appears nonlinear

Standardizing Data and the Normal Distribution Part 2
von Lourdes K. am 20. Oktober 2017 für Standardizing Data and the Normal Distribution Part 2

I learned a lot with this lecture. Really, I like the way of explanation. I will recommend this lecture to everybody who is really wanted to study statistics.
