What is the mode of a line plot?
When students are familiar with reading line plots, introduce them to the different ways to describe data. Range is the difference between the greatest and least number in a data set. The range for the amount of money students spent on snacks is $5 − $1, or $4. Mode is the number that occurs most often in a data set.
A line plot is a graph that shows the frequency of data occurring along a number line. Line plots provide a quick and easy way to organize data and are best used when comparing fewer than 25 different numbers.
- A line chart or line graph is a type of chart which displays information as a series of data points called 'markers' connected by straight line segments. It is a basic type of chart common in many fields.
- A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit).
- The figures below show an example of a histogram and a bar chart. Histograms are used to show distributions of variables while bar charts are used to compare variables. Histograms plot quantitative data with ranges of the data grouped into bins or intervals while bar charts plot categorical data.
A line plot is a graphical display of data along a number line with Xs or dots recorded above the responses to indicate the number of occurrences a response appears in the data set. The Xs or dots represent the frequency. A line plot will have an outlier.
- Double number line diagrams are best used when the quantities have different units. Double number line diagrams can help make visible that there are many, even infinitely many, pairs of numbers in the same ratio—including those with rational number entries. As in tables, unit rates (R) appear in the pair (R, 1).
16 times 1 16 16 times 2 32 16 times 3 48 16 times 4 1,4 16 times 5 1,20
- To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
Line graphs are like scatter plots in that they record individual data values as marks on the graph. The difference is that a line is created connecting each data point together. In this way, the local change from point to point can be seen.
- When there are two middle numbers, the median is the mean of these two numbers. The median for the amount of money students spent is $3.50. An outlier is a number that is distant from most of the other data. The data shown on this line plot does not have an outlier.
- Linear graphs are one way of expressing these relationships, when graphed they give a straight line. Linear graphs can be sketched or plotted. Plotting a Straight Line Graph.
- How to Create a Line Graph
- Create a table. Draw the x- and y-axes on the page.
- Label each axis. If time is one of the factors, it should go along the horizontal (x) axis.
- Add data. Data for a line graph is usually contained in a two-column table corresponding to the x- and y-axes.
- Create a key.
