Where is the independent variable on a data table?
Ah, the independent variable is typically found on the left side of a data table. It's the variable that you can control or manipulate to see how it affects the dependent variable. Just remember, like a happy little tree, the independent variable helps guide the direction of your experiment.
Does a line graph show the relationship between three variables?
a simple 2d xy line graph has only the possibility for 2 different variables (x and y). for a 3 variable graph you would have to go into a 3d xyz graph with each variable as x, y and z. it is possible to fit a line to this but for an easier analysis it is better to analyse the variables in pairs.
What are the disadvantages of a stacked bar graph?
You can only make a stacked bar graph if one of the groups is always smaller than the other.Otherwise one bar might go right over the other one.* * * * *The above disadvantage does not apply to stacked bars where the bar for each variable is stacked on top of other bars. The main disadvantage is that it becomes increasingly difficult to see changes in all but the variable that is at the bottom of the stack (and so has a fixed bottom line).
What is non example of a dependent variable?
That means finding something that changes, but isn't dependent on something else changing it. I would say that time is a non-example. It keeps changing regardless of how other things are changing. (Now, there is an exception to this in physics, where the passage of time changes in relation to velocity, but we're assuming that we are just talking about time as it is typically for us.) Another example would be something like a quantity purchased. Let's say that candy bars cost $ .75 each. The total cost would be dependent on how many candy bars are purchased, so the total cost would be the dependent variable. The number of candy bars purchased would be the independent variable, since it doesn't depend (within reason) on the total price. Since it is an independent variable, it is not a dependent variable, so it is a non-example of a dependent variable. For example, someone could purchase either 3 or 4 candy bars, and the total price depends on how many are bought, but how many are bought doesn't depend on the total price.
What might a graph show that a data table does not?
The graph could go on forever while a data table only shows a part of the graph.
