Question

23 The relative frequency is the frequency in each class divided by the total number of observations.

A true

B false

24, The scatter plot can visually show the relationship between two variables.

A false

B True

25 Ratio measurement scales indicate both rank and distance from a natural zero.

A true

B false

26

A time series diagram is a bar chart that displays the frequency of defect causes and is used to separate the "vital few" from the "trivial many.

A true

B false

Answer 1

23 The relative frequency is the frequency in each class divided by the total number of observations.

Relative frequency = class frequency/total frequency

A true

24, The scatter plot can visually show the relationship between two variables.

A scatter plot represent values for two different numeric variables using dots. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.

B True

25 Ratio measurement scales indicate both rank and distance from a natural zero.

In Ratio scaled data, values can be ordered, have a meaningful difference, and doubling is also meaningful. There is an True zero.

A true

26 A time series diagram is a bar chart that displays the frequency of defect causes and is used to separate the "vital few" from the "trivial many.

The above is the defination of parato chart

B false
