Different Types Of Graphs

Explanation
A bar graph would be the most appropriate type of graph to show the populations of 5 different cities in Texas. A bar graph uses rectangular bars of varying lengths to represent data, with each bar representing a different category or group. In this case, each bar would represent a different city, and the length of the bar would correspond to the population of that city. This type of graph allows for easy comparison of the populations between the different cities, making it a suitable choice for this scenario.

Explanation
A line graph would be the most appropriate type of graph to show the population change of NYC over the past 70 years. This is because a line graph is commonly used to display data that changes over time. By plotting the population on the y-axis and the years on the x-axis, a line graph would effectively illustrate the trend and fluctuations in NYC's population over the 70-year period. A pie chart would not be suitable as it is used to show proportions or percentages of a whole, while a bar graph and histogram are typically used to compare different categories or groups of data.

Explanation
A double bar graph is the most appropriate graph to show the favorite subjects of boys and girls separately. This graph allows for easy comparison between the two groups by displaying two sets of bars side by side, with one set representing the favorite subjects of boys and the other set representing the favorite subjects of girls. This visual representation helps to clearly illustrate any differences or similarities in the favorite subjects of boys and girls.

Explanation
A bar graph would be the most appropriate type of graph to compare the number of each color smarties. This is because a bar graph uses rectangular bars to represent data, with each bar representing a specific category (in this case, each color of smarties). The length of each bar corresponds to the quantity or frequency of that category, allowing for easy visual comparison between the different colors of smarties.

Explanation
A pie chart would be the most appropriate type of graph to show the proportion of students who own different types of pets. A pie chart uses slices of a circle to represent different categories, with each slice's size corresponding to the proportion it represents. In this case, each slice would represent a different type of pet (cat, dog, fish, bird, and no pet), and the size of each slice would show the proportion of students who own that type of pet. This would allow for a clear visual representation of the distribution of pet ownership among students.
