Interpreting Graphs

What is the purpose of a bar chart?

• To display numerical data

• To show trends over time

• To represent geographical data

• To visually represent categorical data and compare different categories or groups.

How can you make comparisons using bar charts?

• By comparing the widths of the bars.

• By comparing the labels of the bars.

• By comparing the colors of the bars.

• By comparing the lengths or heights of the bars.

What information can you record from a bar chart?

• Colors used in the bar chart

• Categories and corresponding values or frequencies

• The source of the data for the bar chart

• The title of the bar chart

What is the main difference between a bar chart and a line graph?

• A bar chart and a line graph are the same thing.

• A bar chart uses lines to represent data categories, while a line graph uses bars to show the trend or change in data over time or another continuous variable.

• A bar chart uses bars to represent data categories, while a line graph uses lines to show the trend or change in data over time or another continuous variable.

• A bar chart is used for qualitative data, while a line graph is used for quantitative data.

How can you interpret a simple line graph?

• By looking at the color of the lines

• By counting the number of lines

• By measuring the length of the lines

• By analysing the slope and direction of the lines, you can interpret the trend or pattern in the data.

What does the x-axis represent in a line graph?

• The x-axis represents the independent variable.

• The x-axis represents the average of the data points.

• The x-axis represents the dependent variable.

• The x-axis represents the error margin.

What does the y-axis represent in a line graph?

• independent variable

• slope

• x-axis

• dependent variable

What are some key features to look for when interpreting a bar chart?

• Color, font size, background, axis

• Legend, gridlines, data points, axis labels

• Title, background color, font style, data points

• Title, labels, scale, bars, annotations

What are some key features to look for when interpreting a line graph?

• color, title, legend, data points, gridlines

• color, title, legend, data points, labels

• title, legend, data points, gridlines, labels

• trend, slope, axis labels, units, significant points
