D)Frequency polygon

Accepted Answer

B

Question 3

What does a histogram show?
A)A histogram is a graph in which values of observations are plotted on the horizontal axis,and the frequency with which each value occurs in the data set is plotted on the vertical axis.
B)A histogram is a graph in which values of observations are plotted on the horizontal axis,and their density is plotted on the vertical axis.
C)A histogram is a graph in which levels of the independent variable are plotted on the horizontal axis,and the mean of observations is plotted on the vertical axis.
D)A histogram is a graph in which values of one variable are plotted against values of a different variable.

Accepted Answer

A histogram shows the distribution of a set of continuous data. It consists of a bar graph in which the values of observations are plotted on the horizontal axis, and the frequency with which each value occurs in the data set is plotted on the vertical axis. Each bar represents a range of values, and the height of the bar represents the frequency of the observations falling within that range.

Question 4

Imagine we took a group of smokers,recorded the number of cigarettes they smoked each day,whether they wanted to quit smoking or not,and then split them randomly into one of two 6-week interventions; 'hypnosis' or 'nicotine patch'.After the 6 weeks,we again recorded how many cigarettes they smoked each day and subtracted this number from the number of cigarettes they each smoked pre-intervention,to produce an intervention success score for each participant.Out of the following options,which would be the best method of looking at which intervention was the most successful,taking into account whether the participant wanted to quit or not?
A)Clustered boxplot
B)Frequency polygon
C)Simple histogram
D)Population pyramidb.

Accepted Answer

A clustered boxplot would allow us to compare the intervention success scores of the two groups (hypnosis and nicotine patch) while also taking into account whether the participants wanted to quit or not. The two boxes for each group could be split into those who wanted to quit and those who did not, allowing for a more nuanced analysis of the data. A frequency polygon, simple histogram, and population pyramid would not be as effective in comparing the success of the interventions while considering the participants' desire to quit.

Question 19

Imagine we took a group of smokers,recorded how many cigarettes they smoked each day and then split them randomly into one of two 6-week interventions; 'hypnosis' or 'nicotine patch'.After the 6 weeks,we again recorded how many cigarettes they smoked each day and subtracted this number from the number of cigarettes they each smoked pre-intervention,to produce a intervention success score for each participant.Out of the following options,which would be the best method of displaying the results?
A)A simple bar chart with the variable 'intervention method' on the y-axis and 'intervention success' on the x-axis.
B)A simple boxplot with the variable 'intervention method' on the x-axis and 'intervention success' on the y-axis.
C)A clustered boxplot with 'intervention success' on the y-axis and 'intervention method' on the x-axis
D)A simple boxplot with the variable 'intervention method' on the y-axis and 'intervention success' on the x-axis.

Accepted Answer

A simple boxplot with 'intervention method' on the x-axis and 'intervention success' on the y-axis is the best method because it allows for easy comparison between the two intervention groups while displaying the distribution of the intervention success scores, including the median, quartiles, and potential outliers.
