I have collected data on the number of people attending rock concerts a Melbourne venue. I have data for concerts for Green Day, Pink, Metallica, Bruce Springsteen, Birds of Tokyo.
I should display my data using a :
Correct Answer
A. Bar Chart
Explanation
A bar chart is the most suitable way to display the data on the number of people attending rock concerts at a Melbourne venue. A bar chart uses rectangular bars of equal width to represent the frequency or count of each category, in this case, the number of people attending each concert. The height of each bar corresponds to the count, allowing for easy comparison between different concerts. This type of chart is commonly used to visualize categorical data and is effective in showing the differences in attendance between concerts.

I have measured the heights of all the students in my class - there are 25 students.
I should display my data using a :
Correct Answer(s)
D. Histogram with class/interval > 1
F. Stem and Leaf Plot
Explanation
The correct answer is Histogram with class/interval > 1, Stem and Leaf Plot. Both of these methods are suitable for displaying quantitative data, such as the heights of the students in this case. A histogram with class/interval > 1 would group the heights into intervals, allowing for a visual representation of the distribution of heights. A stem and leaf plot, on the other hand, would show each individual height value, providing a more detailed representation of the data. Both methods are effective for displaying the measurements of the students' heights.

I have found the number of TV sets in each household of the 25 students in my class.
How should I display my data?
Correct Answer(s)
C. Histogram with intervals of 1
F. Stem and Leaf Plot
Explanation
The correct answer is Histogram with intervals of 1 and Stem and Leaf Plot because both of these methods are suitable for displaying data that is continuous and can be measured on a numerical scale, such as the number of TV sets in each household. A histogram with intervals of 1 would show the frequency distribution of the data, with each interval representing a range of values. A stem and leaf plot would also show the distribution of the data, with the stems representing the tens digit and the leaves representing the ones digit of each value. Both methods would provide a clear visual representation of the data.
