Explanation / Answer
Let us check each of them:
a Bar chart - The bars represent a variable that is not measurable. For instance we can have the revenue per year. The year is merely a label. Therefore, this is qualitative.
b Stem and Leaf - Each value (stem or leaf) is a measurable quantity or a numbers. Therefore, this is quantitative.
c Dot Plot - Each value is a measurable quantity or a numbers. Therefore, this is quantitative.
d Histograms - A histogram differs from a bar graph in that the bars actually represent values. Therefore, this is quantitative.
e Pie Chart - A pie chart shows percentage or slice for a group of labels which are not quantitative. For e.g the market share of all vendors. This is qualitative.
f Frequency Distribution Table - Both the values and their frequencies are numerical values. This is quantitative.
g Frequency Table - This table simply consists of labels and frequencies. This is qualitative.
Therefore, the answers are:
1. a e g
2. b c d e
