What is independent and dependent variable in quantitative research?
The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
Can an independent variable be quantitative?
Some examples of quantitative variables are height, weight, and shoe size. In the study on the effect of diet discussed above, the independent variable was type of supplement: none, strawberry, blueberry, and spinach. The variable “type of supplement” is a qualitative variable; there is nothing quantitative about it.
What is the independent variable on a graph?
The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).
Where is the independent variable on a table?
In most data tables, the independent variable (the variable that you are testing or changing on purpose) will be in the column to the left and the dependent variable(s) will be across the top of the table.
What is the independent variable in a bar graph?
The independent variable here is the YEAR and it is plotted on the horizontal axis. The dependent variable is the AVERAGE HEIGHT and this is plotted on the vertical axis. The height is a dependant variable because we are trying to determine a relationship between the year and the height.
What is vertical bar graph?
vertical bar graph. vertical bar graph. A graph that visually displays data using vertical bars going up from the bottom, whose lengths are proportional to quantities they represent. It can be used when one axis cannot have a numerical scale. English | Español.
What type of data is graphed with a circle graph?
A circle graph/pie chart is a way of summarizing a set of categorical data or displaying the different values of a given variable ( e.g. , percentage distribution). This type of chart is a circle divided into a series of segments. Each segment represents a particular category.
What type of graph should I use?
. . . a Line graph. 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 are circle graphs best used for?
A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.
Which type of graph is helpful for comparing quantitative data?
Bar graphs
What does a frequency distribution show?
Frequency distribution, in statistics, a graph or data set organized to show the frequency of occurrence of each possible outcome of a repeatable event observed many times.
