It means that your observation of the subject in question has not been constant or to plan.
The controlled variable is the variable that is kept constant , meaning not changed, throughout the entire experiment.
Observation-Seeds placed in cotton germinate the same as seeds placed in soil, Hypothesis- Seeds do not need soil for germination Manipulating variables- soil, cotton Responding- height of seeds germinated
The Scientific Method 1) Observe- use the five senses 2) Hypothesis- a proposed explanation for observation; an educated guess 3)Experiment- a procedure used to test a hypothesis -find the independent variable(variable that changes during experiment) -Find the dependent variable(variable that changes in response to the idependent variable) 4) data- write down everything you observe about the experiment. 5) Conclusion!!!!
A quantitative observation is one that involves measuring or quantifying a particular attribute or variable. For example, counting the number of flowers in a garden, measuring the temperature of a room, or determining the weight of an object are all examples of quantitative observations.
Systematic observation includes naturalistic observation, which is real-life observation, and structured observation, which takes place in a natural environment in which manipulation is involved
Why does a Percent correct on a memory task is an example of a variable with a scale of measurement and is a numerical observation.?
You can know which is the variable in a laboratory just by observation. The number of times that it has been used in the different procedures will also help you tell which is the variable.
observation
It is a continuous variable. BUT as soon as you measure it, the limitations of your timing device make the observation a discrete variable - even if you can measure with an accuracy of a nanosecond.
ratio
Variable means something that changes. X, for example, is a variable, as it can be many different numbers.
what did yousee,what happen? describe it
observation is a qualitative research method, and therefore has the previously identified strengths and weaknesses
variable is the unknown number. usually represented as a letter
An independent variable is a variable that is manipulated or controlled by the researcher in an experiment to determine its effect on the dependent variable. It is the variable that is changed or varied to observe its impact on the outcome.
The controlled variable is the variable that is kept constant , meaning not changed, throughout the entire experiment.
The dependent variable depends on the independent variable for its values as for example in the straight line equation y = 2x+6 whereas y is the dependent variable and x is the independent variable
