NAME TWO OF THE FIVE STEPS OF THE SCIENTIFIC METHOD

observation, hypothesis

______________ IS AN UNPROVEN CONCLUSION THAT ATTEMPTS TO EXPLAIN SOME PHENOMENA. USUALLY IN THE FORM OF A QUESTION/ TESTABLE/ AND BASED ON MEASURABLE DESCRIBABLE FACTS

hypothesis

_________________ IS A LOGICAL, PRACTICAL, AND RELIABLE WAY OF APPROACHING AND SOLVING PROBLEMS TO GAIN KNOWLEDGE, IT COMPRISES 5 MAJOR STEP

scientific method

______________ OBSERVATIONS ARE MADE USING THE SENSES (HEARING, TASTING, SEEING, SMELLING, TOUCHING)

qualitative

____________ OBSERVATIONS ARE BASED ON PRECISE MEASURMENTS, EXAMPLES ARE VOLUME, MASS, SIZE.

quantitative

_____________ IS A PROCEDURE DESIGNED TO DESCRIBE THE FACTORS IN A GIVEN SITUATION THAT AFFECT ONE ANOTHER (TO DISCOVER A CAUSE AND EFFECT) UNDER CERTAIN CIRCUMSTANCES

experiment

A ___________ IS ANY FACTOR THAT MIGHT AFFECT THE OUTCOME OF THE EXPERIMENT

variable

THE ________________ VARIABLE IS MANIPULATED BY THE EXPERIMENTER TO DETERMINE EFFECT ON THE DEPENDENT VARIABLE

independent

THE ________________ VARIABLE CHANGES IN RESPONSE TO CHANGES MADE TO THE INDEPENDENT VARIABLE

dependent

A ________________ IS A NORMAL STANDARD AGAINST WHICH ALL OTHER SAMPLES ARE COMPARED RELATIVE TO THE DEPENDENT VARIABLE

control

THE _____________ IS THE DIFFERENCE BETWEEN THE HIGHEST AND LOWEST NUMBERS OBTAINED IN A SAMPLE

range

THE _______________ IS THE SUM OF THE ITEMS DIVIDED THE NUMBER OF ITEMS

mean/average

A FOCUS FOR INVESTIGATION IS CALLED THE ____________

problem

THE _______________ IS AN ARBITRARY SYSTEM OF MEASURMENT BASED ON UNITS OF TENS

NAME ONE TYPE OF ELEMENTARY TREATMENT OF DATA USED IN THE LAB

calculating average of a dataset

________________ IS AN IMPORTANT PART OF THE SCIENTIFIC METHOD AND IS THE PRIMARY BASIS FOR SUPPORT OF REJECTION OF MANY HYPOTHESIS

repeatability

FROM THE LATIN "FOR 100", ________________ MEANS PARTS PER 100 PARTS
