Question 11

Explanation

A. Pie chart A pie chart is the most suitable chart for showing the percentage of defects in different product categories. This is because a pie chart visually represents the distribution of a whole (in this case, the total defects) into its parts (the different product categories). Each category is represented by a slice of the pie, with the size of the slice proportional to the percentage of defects in that category. This allows for easy comparison and understanding of the distribution of defects across different product categories. Additionally, the use of colors and labels in a pie chart makes it visually appealing and easy to interpret. B. Scatter plot A scatter plot is not suitable for showing the percentage of defects in different product categories. Scatter plots are used to display the relationship between two continuous variables, typically with one variable on the x-axis and the other on the y-axis. In this case, the question is asking for a visualization of the distribution of defects in different product categories, which involves categorical data rather than continuous variables. Therefore, a scatter plot would not effectively represent the data and may lead to confusion or misinterpretation. C. Line chart A line chart is not the most suitable chart for showing the percentage of defects in different product categories. Line charts are typically used to show trends or changes over time, with one variable on the x-axis representing time and the other on the y-axis representing the value being measured. In this case, the question is asking for a visualization of the distribution of defects in different product categories, which does not involve a time component. Therefore, a line chart would not effectively represent the data and may not provide a clear understanding of the distribution of defects across different product categories. D. Stacked bar chart A stacked bar chart is a suitable chart for showing the percentage of defects in different product categories. In a stacked bar chart, each product category is represented by a bar, and the height of the bar represents the total percentage of defects in that category. The bar is then divided into segments, with each segment representing the percentage of defects within a specific subcategory. This allows for easy comparison of the percentage of defects across different product categories and within each category. The use of colors and labels in a stacked bar chart makes it visually appealing and easy to interpret.
