Evaluating how accuracy and reliability could be improved in investigations and account of how to perform a successful experiment. The term reliability refers to the consistency with which we can confirm the result. The need for accuracy of data should influence the choice of equipment for conducting first hand investigations, where data is collected, quantified or evaluated, reliability refers to the consistency of the information, validity refers to whether the measurements you are taking are …showed first 75 words of 668 total…

…showed last 75 words of 668 total…sort of is what validity is about. but a sub branch of it...and that includes things such as the systematic error...for example the scale of a weight or the measurements on an old ruler may have systematic error...and also something destroying an accuracy of an experiment may be also caused by parallax error which is the way you observe a measurement perhaps....1 more advice...accuracy...u can show it as a percentage.
