Data and Graphs

What is a tally chart?

• A method to record and count data using marks (tallies) to show occurrences.

• A type of graph that displays data in a circular format.

• A statistical tool used to analyze trends over time.

• A chart that lists items in alphabetical order.

What is a bar graph?

• A visual representation of data using bars of different heights or lengths to show the quantity of each category.

• A type of graph that uses lines to connect data points.

• A circular chart divided into sectors to illustrate numerical proportions.

• A method of displaying data in a table format.

What is a picture graph?

• A type of graph that uses only numbers to represent data.

• A graph that uses images or symbols to represent data, making it easy to understand at a glance.

• A graph that displays data in a linear format without any visual aids.

• A graph that compares two different sets of data using colors.

What is the total number of students if 3 students had more than 6 candy bars?

• The total number of students is 10.

• The total number of students is not directly given; this question requires additional context from the graph.

• The total number of students is 5.

• The total number of students is 15.

How do you find the difference in quantities using a graph?

• By adding the values of the bars or points on the graph.

• By comparing the heights or lengths of the bars or points on the graph.

• By calculating the average of the values represented on the graph.

• By counting the number of bars or points on the graph.

What is the purpose of using graphs?

• Graphs help to visually represent data, making it easier to understand and compare different sets of information.

• Graphs are used to create artistic representations of data.

• Graphs are primarily used for statistical calculations and formulas.

• Graphs serve as a decorative element in presentations.

How can you compare two categories in a graph?

• By looking at their values on the graph and determining which one is larger or smaller.

• By counting the number of data points in each category.

• By analyzing the color differences in the graph.

• By measuring the distance between the two categories on the graph.

How can you tell which category is the highest in a bar graph?

• The highest bar in a bar graph represents the category with the greatest quantity.

• The lowest bar in a bar graph represents the category with the least quantity.

• The color of the bar indicates the highest category.

• The width of the bar shows the highest category.

How do you read a bar graph?

• Look at the labels on the x-axis and y-axis to understand the data being represented.

• Only focus on the tallest bar to interpret the data.

• Ignore the labels and just count the number of bars.

• Read the graph from right to left for accurate information.

What does it mean to have 'more' in a graph?

• It means that one category has a greater quantity than another category, which can be seen by comparing their values on the graph.

• It indicates that the graph is incorrectly labeled and needs correction.

• It suggests that the graph is showing a decrease in values over time.

• It means that the graph is comparing unrelated categories.
