What is a line graph ks3?
A line graph is often used to show a trend over a number of days or hours. It is plotted as a series of points, which are then joined with straight lines. The ends of the line graph do not have to join to the axes.
How do you describe data on a line graph?
A line graph plots data in a single line over time. To describe the graph, follow it’s progress along the horizontal access and describe whether it goes down, up, or stays the same.
What type of data is represented in a line graph?
Line graphs are usually used to show time series data – that is how one or more variables vary over a continuous period of time. A line graph displays that change continuously over periods of time. This graph is useful for representing the data which keeps changing over time. A line graph is also known as a line chart.
What is a line graph ks2?
A line graph is used to represent information which changes over time. A line graph is plotted with points that are joined to create a straight line. Children begin to learn about line graphs in Year 4 and 5, before creating their own in Year 6. Line graphs help with representing a value over time.
What is a line graph used for?
Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.
What is line graph in geography?
Line graphs show how data changes over time or space. The x-axis shows time or distance. A line chart could be used to show the changes in a country’s employment structure over time.
What is line graph in graph theory?
The line graph H of a graph G is a graph the vertices of which correspond to the edges of G, any two vertices of H being adjacent if and only if the corresponding edges of G are incident with the same vertex of G.
A line graph is often used to show a trend over a number of days or hours. It is plotted as a series of points, which are then joined with straight lines. The ends of the line graph do not have to join to the axes.
How do you represent data in a graph?
When you collect and record data, you can represent it in a diagram. To show the results you can use a bar chart, pie chart, line graph, pictogram, frequency diagram or scatter diagram. A line graph is often used to show a trend over a number of days or hours. It is plotted as a series of points, which are then joined with straight lines.
What is the main activity on the graph?
The main activity is three – way differentiated and can be downloaded separately. There are lots of opportunities for rich discussions on interpreting the graphs. The green activity shows nicely how moving averages smooth data (using more points does more smoothing), but can also move peaks and troughs.
What type of graph is used to show results?
To show the results you can use a bar chart, pie chart, line graph, pictogram, frequency diagram or scatter diagram. The type of graph you use depends on the type of data you want to represent. Discrete data is best represented using bar charts.
