What type of data is represented by a frequency table?

• Bivariate data

• Univariate data

• Multivariate data

• Qualitative data

When constructing a scatter plot, what is typically placed on the x-axis?

• Dependent variable

• Independent variable

• Frequency

What does a positive correlation in a scatter plot indicate?

• As one variable increases, so does the other

• There is no relationship between the variables

• As one variable increases, the other decreases

• The variables are inversely proportional

Which of the following is an example of a negative correlation?

• As the number of hours worked increases, pay increases

• No correlation

• Negative correlation

• Positive correlation

What is the purpose of a 'line of best fit' in a scatter plot?

• To show the average value of the data

• To connect all the data points

• To separate different data sets

• To indicate the trend of the data
