1. a data analyst has to create a visualization that makes it easy to show which of the top ten most populous cities in north carolina have a population below 250,000 people. what type of chart would be best for this visualization? scatter chart line chart pie chart bar chart

Explanation:

To determine the best chart for showing the top ten most populous cities in North Carolina with populations below 250,000, we analyze each option:

• Scatter chart: Used to show the relationship between two variables (e.g., population vs. another metric), not suitable for comparing discrete categories (cities) and their populations.
• Line chart: Ideal for showing trends over time or continuous data, not for comparing discrete categories like cities.
• Pie chart: Used to show proportions of a whole, but we need to compare individual city populations, not their proportion of a total.
• Bar chart: Perfect for comparing the values of different categories (cities) by using bars of different lengths to represent their populations. This allows easy visual comparison of the population sizes of each city.

Answer:

Bar chart (the option labeled "Bar chart")
