In the field of science, the different types of data often leads to disagreement and separate conclusions based on this data. In science, the two main types of data are quantitative and qualitative; quantitative data being data that can be measured in numbers while qualitative data being data that can be observed and described. Quantitative data tends to not only be more precise, but also easier to reproduce. On the other hand, qualitative data is measured based on the scientist’s interpretations of a certain quality within an experiment. For example, when performing titrations, scientists often use color indicators to show when the titration is complete. However, they must decide for their own when the color has changed sufficiently for the titration to be considered complete. This leads to a large amount of room for error. This same experiment can be performed around the world several times by experts in the field of science yet they may all come to different conclusions about the data.This imprecision of this data leads to the question of the extent to which the preconceived ideas of scientists affects the way they interpret data. Often times in science, data is either difficult to describe, as in the exact color of a solution when a titration is complete, or in instances where an experiment cannot be conducted in order to test a theory. For example, String Theory was proposed by scientists years ago and many scientists continue to support it today. In the words of Richard Dawid, “On one side of the divide stand most of those physicists who work on string physics and in fields like inflationary cosmology or high energy particle physics model building, which are strongly influenced by string physics.” Yet, many other experts disagree and refuse to support the theory. They, “consider string theory a vastly overrated speculation,” and without being able to conduct an experiment to prove the theory, it is not valid. They refuse to consider the evidence proposed by scientists who support the theory simply based on this single idea.
