what is the difference between a line graph and a scatter plot quizlet?

A line graph uses both the x- and y-axes, while a scatter plot only uses the y-axis. ... A line graph presents continuous and linked data, while a scatter plot presents unlinked data. You just studied 10 terms!

Examine the equation for the line, which Excel is now displaying overlaid on the scatter plot. The equation will be in the form of "y = mx + b" where m and b will be numbers. The value of "m" is the slope of the graph. For example, if the equation is y = 5.2x + 7, the slope is 5.2.

Statistics » Frequency polygon / line graph A frequency polygon is a line graph. The points are often not connected with a smooth line, but with straight line segments. Frequency polygons are used to show the changes over time.

A histogram represents the frequency distribution of continuous variables. Conversely, a bar graph is a diagrammatic comparison of discrete variables. Histogram presents numerical data whereas bar graph shows categorical data. The histogram is drawn in such a way that there is no gap between the bars.

All graphs have an x and y axis. Coordinates, written as an ordered pair of numbers, are used to give positions on a graph. The x-axis is horizontal (across), while the y-axis is vertical (up-down).

The relationship between two variables is called their correlation . Scatter plots usually consist of a large body of data. The closer the data points come when plotted to making a straight line, the higher the correlation between the two variables, or the stronger the relationship.

Scatter Plots (also called scatter diagrams) are used to investigate the possible relationship between two variables that both relate to the same "event." A straight line of best fit (using the least squares method) is often included.

The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis. ... an x-intercept is a point on the graph where y is zero, and. a y-intercept is a point on the graph where x is zero.

A line graph only has one line of data. ... A stacked line graph will follow the same structure — x-axis, independent, y-axis, dependent, plot and connect — but will consist of more than one line plotted on the same graph. Each line represents a different “thing” that was studied.

Plot is the five main components of a story, shown in the diagram above. A summary, is a describing the main points in the story in a couple of sentences. ... So no, a summary isn't the same thing as plot.

The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.

Line graphs are used to display data or information that changes continuously over time. Line graphs allow us to see overall trends such as an increase or decrease in data over time. Bar graphs are used to compare facts. The bars provide a visual display for comparing quantities in different categories or groups.

The advantage to using graphs and charts is that they can display a lot of information is an easy to understand format. For example, a line graph is a great way to show trends over a period of time. You could put numbers in a table, but a line that is consistently going up is much more accessible at a quick glance.

Ask: How are bar graphs and picture graphs different? Bar graphs use bars and numbers to show information; picture graphs use pictures to show information. With a picture graph you need to count each time to find how many, but with a bar graph you can just look at the bars and numbers.

Waveform Graphs and Waveform Charts differ in the way they display and update data: A Waveform Graph accepts arrays of data in various forms, e.g. array, waveform, or dynamic data. ... A Waveform Chart remembers and displays a certain number of points by storing them in a buffer.

Different types of graph are used to represent statistical data . The most common types are line graphs, bar graphs and pie charts.
