This section helps you in understanding how to formulate an action hypothesis. Objectives After reading this material and performing the activities listed, you will be able to acquire knowledge about hypothesis and Action Hypothesis. Overview In the last chapter we discussed how a problem could be selected for Action Research. We also saw how we can go about identifying the specific problem, At this stage we need to think and generate a list of alternative causes for the pin-pointed problem.
Every science experiment should follow the basic principles of proper investigation so that the results presented at the end are seen as credible. Observation and Hypothesis Observing a new physical process or phenomenon is a rare event, but there are areas of science that are not fully understood.
The scientist must put his observations into words to develop a meaningful hypothesis. The hypothesis has to explain the phenomenon using a mechanism or a mathematical relationship, as described by Professor of Physics Frank L.
Wolfs at the University of Rochester. Prediction and Modeling It is not enough to guess why something is happening. A scientist must prove his theory is correct. Predictions are made to test the observations under different circumstances. The aim is to discover more about the phenomenon and to prove it exists.
Each experiment has to be planned to reduce the number of variables. It is never enough to say an experiment was conducted and upholds the theory but that the method or results are not available. Every experiment will contain a small area of error. If the theory is to be proven using mathematics, deviations about the mean are applied to the result of each calculation.
Result Gathering and Presentation Scientists must record their results. Often, the original theory can be rewritten after experimentation to illustrate new phenomena. If the experiments conducted do not support any theory, they must be rejected.
Each result must be double-checked and those which clearly do not fit the pattern are analyzed further. Once the results are collated, they can be presented as a table, graphs, diagrams or computer graphics. Each representation must support the original theory.
Conclusions When the results are in and have been presented in meaningful ways, conclusions can be drawn. A conclusion involves interpreting the results, recognizing any patterns present and describing what those patterns and interpretations mean in reality. Any modeling or prediction must be converted into a meaningful, reasoned conclusion.
The conclusions of single experiments can be developed into predictions of entire behaviors and further ideas about testing. Law Formation One of the main aims in science is to discover and prove new laws that explain how things work. When two or three models are formulated based on initial observations, and the theory is successfully tested, the different models can be drawn together.
An example of a single concept law is the First Law of Thermodynamics. References University of Rochester: Error Analysis; Frank L.

Power of Prediction. One of the valuable attribute of a good hypothesis is to predict for future. It not only clears the present problematic situation but also predict for the future that what would be happened in the coming time. characteristics of a good hypothesis A good hypothesis must be based on a good research question.
It should be simple, specific and stated in advance (Hulley et al., ). A good research hypothesis should contain three main sections. These are; identifying what the variables and relationships are of what you are experimenting. Aug 28, · Best Answer: it has to be testible, falsifiable, based in factual evidecnce, and be accuratly written in scientific method notation (ie, if this, then that) if a moth is darker in color, then the dark moths will survive predation better in darker environments is an example it's testable (get light and dark moths, see who get's predated most)Status: Resolved.
Read this article to learn about the meaning, criteria for formulation and types of hypothesis. There exist two criteria for formulation of a good hypothesis.
First, it is a statement about the relations between variables. that a particular object, situation or event has certain characteristics.
It may be in the form of counting the. The key characteristic of a good hypothesis is the ability to derive predictions from this hypothesis about the results of future experiments, then performing those experiments to see whether they.
