it is the variable that you change during an experiment and is placed on the x axis.
for example, if you are checking for the effect of light intensity on water uptake by a plant, the independent variable is the different light intensity values that you have and the dependent variable is the rate of water uptake which will be on the y axis.
what you change and dependent variable is what you measure. :) Also, generally the independent variable goes on the x axis of any given graph, while the dependent goes on the y axis (except for specific types of graph characterized by their shape, such as rate of reaction graphs in chemistry)
The variable deliberately changed in an experiment is called the independent variable. This variable is manipulated by the researcher to observe its effects on the dependent variable, which is the outcome or response being measured. By controlling and changing the independent variable, researchers can determine its influence on the dependent variable.
In a controlled experiment, the one factor that differs is the independent variable. This is the variable that is deliberately changed or manipulated by the researcher in order to observe its effect on the dependent variable. The goal of a controlled experiment is to isolate the impact of the independent variable on the dependent variable while holding all other variables constant.
A dependent variable is the outcome that is being measured or tested in an experiment or study. It is influenced by the independent variable, which is the variable that is manipulated. The dependent variable is what researchers are trying to understand or predict based on the changes in the independent variable.
Temperature can be both an independent variable, where it is manipulated to observe its effect on other variables, or a dependent variable, where it is measured as an outcome of other factors. The role of temperature as a dependent variable or independent variable depends on the specific research context.
it has something to with mathematical graphs
Graphs showing the relationship (or not) between two independent variables.
An independent variable is not affected by the change of another independent variable. To make an experiment, you generally try to change each independent variable in its turn, leaving other independent variables constant, getting the result (the dependent variable) which was chosen. The results can be exhibited as graphs, where the independent variable serves as abscissa or a parameter, or tables

The value measured by the vertical axis is typically referred to as the "dependent variable." This variable is influenced by changes in the independent variable, which is usually plotted on the horizontal axis. In graphs, the dependent variable's value is what researchers or analysts aim to observe or measure in response to variations in the independent variable.
Bar graphs are used when graphing a qualitative independent variable, but a line graph is used when the independent variable is quantitative. Also when you are comparing quantity of objects(bar graph)

Graphs visually represent the relationship between responding variables and independent variables, allowing for easy analysis of trends and patterns. By plotting data points on axes, where one axis represents the independent variable and the other the responding variable, viewers can quickly assess how changes in the independent variable influence the responding variable. This visual representation helps in identifying correlations, trends, and potential causal relationships, facilitating better understanding of the data.
Bob thought that the independent variable in our experiment about wait times should be time of day, but I thought it more likely that the wait time varied according to day of the week. In the end, we printed graphs showing the results for both.

The usual way is to plot the independent variable on the horizontal, and the dependent variable on the vertical. There are some where the dependent is on the horizontal, though. Supply-Demand and Price graphs in Economics comes to mind, as an example.
The independent variable.
