Is testing a group of 10 volunteers' blood pressure before and after exercise an example of an independent or dependent sample?

What you have written is the test...an independent variable may be something like the type/length of exercise, the dependant variable in this case is the blood pressure.

Is sandpaper a dependent variable?
I really can not answer this question. Variables represent outcomes, properties, qualities or events. A good example of a dependent variable related to sandpaper is the amount of wood is removes. Now, this variable will depend on many factors. Can you think of some? a) The amount of time that you sand b) The roughness of the sandpaper c) The size of the piece of wood you are sanding d) The hardness of the wood you are sanding e) The pressure that you apply when you are sanding I can come up with many more independent variables if I include sanding by hand or using a machine.
Is blood pressure a discrete variable?
No. Because blood pressure is continuous variable. Like temperature, a person's weight and height, the measured value occurs over a continuous scale.
What is the formula used to calculate probability?
force over area=pressure
Is 213 over 129 okay for blood pressure?
No, that's very high.
What is the function of residual volume?
The function of residual volume is to keep enough pressure in the lungs to keep them from collapsing.
what are the dependent and independent variables of a ballon depending on atmospheric pressure?
The mass of the balloon is independent. Atmospheric pressure will not change this because atoms are not being added or taken away from the balloon itself or its contents. The volume of the balloon will change, however, as it will expand or compress in response to the atmospheric pressure around it. The volume, therefore, is a dependent variable in this situation.
What is dependent variable between age and blood pressure?
The dependent variable would be blood pressure. The independent variable would be age. Of course, there are many factors, other than just age, which determine blood pressure.
What is an Independent Variable and a dependant variable?
temperature, pressure , volume, are independent density, viscosity, etc are dependent Properties of mater are always dependent of independents. as (dependent) density , viscosity , mass density , phase conduction , etc always vary when we change independents .(temperature, pressure , volume) so you can understand dependent & in dependent
How do you test two independent variables and one dependent variable?
Independent variable is what you change in the experiment group. Dependent variable is what happens because of the independent variable. It has to be measurable in degrees, inches, or other such measurements.
Why pressure is on y axis only?
It is only on the Y-axis if it is a dependent variable. However that only applies if the Y-axis is the dependent variable. Pressure could be on the X-axis if it were a situation where pressure would be deemed an independent variable i.e. saturation temperatures based on pressures. the fact that it is pressure is not enough to deem it a dependent variable. other factors must be taken into account
The velocity of sound in air is independent of change in what variable?
The velocity of sound in air is independent of changes in frequency. Sound waves travel at a constant speed determined by the properties of the medium they are traveling through, such as air temperature and pressure.
What are 2 density dependent and independent factors to the tundra biome?
Density-dependent factors in the tundra biome include food availability and predation pressure, where populations increase or decrease based on these factors. Density-independent factors include temperature fluctuations and weather conditions, which can impact survival regardless of population density.
What is the dependent variable that shows how the volume of gas changes with changes in temperature?
The volume of gas
What is an independent variable in statistics?
In a statistical model you have two kinds of variable. Response variables are the "outputs" of your model. Explanatory variables, on the other hand, are the "inputs" of your model. Response variables are dependent on the explanatory variables. Explanatory variable are independent of the response variables.Imagine you were trying to formulate a statistical model of your car's fuel economy. The "output" of your model is miles per gallon (or kilometres per litre). That's a dependent variable. "Inputs" into your model might be (for example) engine capacity, number of cylinders, tyre pressure, etc. These are your independent variables. That is, fuel economy may be, or is, (to be determined by the modelling) dependent on engine capacity and/or number of cylinders and/or tyre pressure, etc.
What kind of pressure of a liquid is the pressure exerted at equilibrium and is dependent on temperature only?
Vapour pressure ; yes
Saturation Vapor Pressure is dependent on what variable?
Temperature
Why is the equilibrium constant independent of wavelength?
The equilibrium constant is independent of wavelength because it represents the balance of reactants and products in a chemical reaction, which is determined by the thermodynamics of the reaction and not by the specific wavelength of light that may be used to drive the reaction. The equilibrium constant is dependent on temperature, pressure, and concentrations of reactants and products, but not on the wavelength of light.
