PPT-Scientific Measurement Chapter 3

Measurements and Their Uncertainty 31 31 Measurements are fundamental to the experimental sciences For that reason it is important to be able to make measurements and to use them correctly when calculating answers. Many teaching techniques are evolved and sug gested to develop scientific attitude Some out of them are the outcome of elaborate efforts of researchers The challenge remains with the measurement of effects of these techniques In other words it is a I.

Curtin University, Perth, Western Australia. Jennie L. Borders. Section 3.1 – Measurements and Their Uncertainty. A . measurement. is a quantity that has both a . number. and a . unit. .. The . unit. typically used in the sciences are those of the . scientific method. . You can use a scientific method to search for the answer to a question. . Scientific methods can vary from case to case, depending on the question and how the researcher decides to look for an answer.. Qualitative. = descriptive, non-numerical.. . ex. : the mornings are getting very cold.. Quantitative. = numerical, definite measurement. . ex. : the temperature was 65°F this morning..
