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
Observation
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.
interference - you give meaning of what you had observed observation- is what you see
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.
what did yousee,what happen? describe it
observation is a qualitative research method, and therefore has the previously identified strengths and weaknesses
ratio
Variable means something that changes. X, for example, is a variable, as it can be many different numbers.
Fetoscopy is direct observation of the fetus and surrounding tissue.
variable is the unknown number. usually represented as a letter
