Railing cost will be affected by intricacy of the design of the railings and baluster, number of posts, type of material, type of mount, curve, etc. Regardless, if you hire a professional carpenter to fix or install your stair railings, you can be sure that you and your family are safe.
Your basic choices are bar graph, line graph, pie chart, or scatter plot. BAR GRAPH â This is the most common type for science fair projects. You may select a bar graph when your independent variable is qualitative (categories) or quantitative (numbers). LINE GRAPH â This is the second most common, but frequently used incorrectly, so be careful here. You should only select a line graph if your independent variable is quantitative (numbers) and you hypothesized that the changes in the independent variable would result in changes in the dependent one.
In calculus, a function is typically graphed with the horizontal axis representing the independent variable and the vertical axis representing the dependent variable. In this function, y is the dependent variable and x is the independent variable.Variable used in an experiment or modelling can be divided into three types:  dependent variable ,  independent variable , or other.The dependent variable represents the output or effect, or is tested to see if it is the effect.The independent variable represents the input or cause, or is tested to see if it is the cause. Other variables may also be observed for various reasons.he term is known as the error and contains the variability of the dependent variable not explained by the independent variable. With multiple independent variables, the expression is: , where n is the number of independent variables.
