Statistics for the Flipped Classroom Quiz

What is the main focus of this lesson?

• Finding the center of the data

• Determining the standard deviation

• Measuring variability

• Calculating the sum of squares

What does variability indicate about the data?

• How consistent the scores are

• How much the scores differ from each other

• The mean of the data set

• The mode of the data set

What term do we use to describe variability in everyday life?

• Dependability

• Stability

• Predictability

• Consistency

What do we like in our data in terms of variability?

• High variability and low consistency

• Low variability and high consistency

• High variability and high consistency

• Low variability and low consistency

What does low variability equal in terms of predictability and consistency?

• Low predictability and high consistency

• High predictability and low consistency

• High predictability and high consistency

• Low predictability and low consistency

What does the mean tell us about the data?

• The mode of the data set

• Where the center of the data is

• How consistent the data is

• The range of the data set

What is the mean of the first data set mentioned in the lesson?

• 6

• 10

• 4

• 8

Which data set has the highest variability?

• Third data set

• Second data set

• Second and third data sets

• First data set

Which data set has the lowest variability?

• First and second data sets

• First data set

• Second data set

• Third data set

What makes the mean less useful in predicting highly variable data sets?

• The mean is not accurate

• The mean is not representative

• The measurement error is higher

• The mean is inconsistent
