Answer 1

Question 9

Answer is a. Continous data as this is only set which can be divided into classes called bins.

The nominal and ordinal is used in bar charts.

Question 10

Answer is d. One way anova as it is bivariate which helps in determining to what extent it becomes easier to know and predict a value for one variable(dependent), if we know the value of other variable (independent). Thus it is the analysis of the relationship between two variables. This can be descriptive and inferential.

The other options are univariate which also can be descriptive and inferential but only fact is that one variable is involved.

Question 11

Answer is c. Skewed to the left. Skewness is the measure of asymmetry in the probability distribution. For a unipolar distribution negative skewness means the tail is at left side of the distribution.
