What is scientific Dependent variable?
A dependent variable is a factor in an experiment that is influenced by another factor. An example might help to clarify. You are performing an experiment in which you are observing how sunlight affects plant height. Plant height is the dependent variable because it is dependent upon how much sunlight the plant receives. Sunlight is an example of an independent variable. It is not influenced by anything in this experiment, but may be changed to observe its effect on the dependent variable. It is possible to have more than one dependent variable in an experiment, but only one independent variable.
What unit of measure can you use to find length and height?
Length and height can be measured in m , cm. It can be measured in feet and inches.
Rebecca is conducting an experiment to see if the height of a ramp affects the speed at which a marble rolls down the ramp What should be the only variable in Rebecca's experiment?
The height of the ramp should be the only variable in Rebecca's experiment. All other factors should be kept constant to isolate the effect of ramp height on the speed of the marble.
What do you use to measure the height of your lab partner?
Height is measured in foot and inch. Centimeter can also be used.
What is metric height?
Metric height refers to the measurement of a person's height using the metric system. In this system, height is typically measured in centimeters or meters. For example, a person who is 170 cm tall has a metric height of 170.
Is the height of a ball's bounce affected by the height from which the ball is dropped dependent and independent variable?
The height from which the ball is dropped is the independent variable, as it is what is being manipulated. The height of the ball's bounce is the dependent variable, as it is what is being measured and is affected by the height from which the ball is dropped.
What kind of variables are the height of the ramp and the mass of a toy car?
The height of the ramp is an independent variable, as it is manipulated by the researcher. The mass of the toy car is a dependent variable, as it is measured based on the height of the ramp.
Can you give some examples of non categorical data?
Non-categorical data, also known as continuous or quantitative data, includes variables that can take on a wide range of values. Examples include height (measured in centimeters), weight (in kilograms), temperature (in degrees Celsius or Fahrenheit), and time (in seconds). These data types allow for mathematical operations and can be measured on a scale, unlike categorical data, which is limited to distinct categories or groups.
What is the difference between a manipulated variable and measured variable?
The manipulated variable is the variable which researches change, while the measured variable is the variable that changes as a result of the manipulated variable. Consider this simplified question: Do flowers grow better with more water? Researchers plant flowers and put 10mL in one pot, 20mL in another, and 30mL in another. This is the manipulated variable. Researchers measure how tall the flowers are. The height of the flowers is the measured variable, because it changes as a result of the amount of water added.
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.
Which is the part of the experiment that is the measurable outcome?
This is the variable which changes as a result of what you change in the experiment. If you change the height from which you drop a ball, you may observe the height to which it bounces. The height of the bounce is the outcome variable.
What are the scientific variables and what do they mean?
In an experiment, the independent variable is the variable that is manipulated, for example plant fertilizer. The dependent variable is what is observed and measured as a result of the independent variable, for example plant height. Controlled variables are factors that are kept constant for the entire experiment, such as temperature and moisture, so that the observed results are due only to the independent variable. So in an experiment measuring the effect of fertilizer on plant growth, the independent variable would be the fertilizer, the independent variable would be the height measured at specific intervals, and the controlled variable of temperature and moisture would be kept the same for both groups.
Can categorical data be continuous?
No, categorical data cannot be continuous. Categorical data consists of distinct categories or groups, such as colors, brands, or yes/no responses, where values represent different classifications rather than quantities. Continuous data, on the other hand, can take any value within a range and is measured on a scale, such as height or temperature. Thus, the two types of data are fundamentally different in nature.
What is the dependent variable in a lava lamp?
The dependent variable in a lava lamp experiment could be the height of the blobs or the speed at which they move up and down. The dependent variable is the aspect of the lava lamp's behavior that is being measured and potentially affected by changes in the independent variable.
What is a variable you change that changes the dependent variable?
The variable you change to affect the dependent variable is called the independent variable. For example, in an experiment measuring plant growth, the amount of sunlight the plants receive is the independent variable, while the growth of the plants (measured in height or biomass) is the dependent variable. By altering the independent variable, you can observe how it influences the dependent variable.
A data table shows the height of a person on his birthday each year for ten years . What is the dependant variable?
In this data table, the dependent variable is the height of the person, as it is the outcome being measured and changes over time. The independent variable is the age of the person, which is the factor that influences the height. Each birthday corresponds to a specific age, and the height recorded reflects the growth that may occur during that year.
What are the independent and dependent variables of how fertilizer affects plant growth?
The independent variable is the thing you are testing or the thing you control. The dependent variable is what you are measuring.
