do? What do biologists do? Biologists study many things. The three main things that they do are that they hypothesis‚ they make observations‚ inferences and they record data. Without hypothesizing‚ biologists can not experiment or create scientific laws. Being able to hypothesis is very important in the world of science. Some evidence that I have‚ to prove that biologists hypothesis‚ are the activities we did in page 17 and in page 28. In page 17‚ in our notebook‚ we did an experiment on

question or problem statement. Problem Statement: How do different ambient temperatures affect the rate of body cooling? 2. Predict a solution to the problem or an answer to the question. This will be in the form of a hypothesis. This solution design or hypothesis should be based on previously obtained knowledge or research and should be supported by scientific evidence. Identify the independent and dependent variables. The independent variable is the variable that is varied or manipulated

starting point of most new research is to formulate a general question about an area of research and begin the process of defining it.This initial question can be very broad‚ as the later research‚ observation and narrowing down will hone it into a hypothesis. For example‚ a broad question might ask ’whether fish stocks in the North Atlantic are declining or not ’‚ based upon general observations about smaller yields of fish across the whole area. Reviewing previous research will allow a general overview

Asch(1951); Crutchfield(1955) and Mann(1969). The aim of the study was; guessing how many sweeties were in the jar in a competition fashion and testing if the participants conformed to their guesses. The hypothesis was ’ people would conform under group pressures of the pre-set guesses. The null hypothesis was that people would not conform under group pressures unless due to extraneous variables. The experiment was a field experiment using the techniques of independent groups design. The experiment was

experiment consisted of 15 psychology students‚ 4 males and 11 females ranging in age from 22 to 45. The hypothesis for this experiment was that participants will be able to identify and recognise more faces in the experiment that have external features rather than internal features‚ causing participants to have fewer errors for images with external features. The results supported the hypothesis as there were fewer number of errors with recognition with external features. This represents that we have

analyst states the problem based on contemplations. Next‚ a hypothesis is formed‚ which means the analyst made an educated guess (solution) to the problem. Before an experiment is performed the analyst has to make a prediction. A prediction is what the person assumes the outcome of the experiment will be‚ if their hypothesis is precise. When making a prediction it is stated in a manner of “if…..then…” Then the analyst tests the hypothesis. The experiment is manipulated so that changes to one variable

Compare this with the chi–square value you calculated in your Lab Notebook. What can you say about the null hypothesis? It is 3.84. Compare this to the chi-square value you calculated earlier.

I predict‚ or foresee the outcome of my investigation to be that my neighbor’s use of K-gro brand fertilizer results in this abundance of tomatoes that is nearly twice that of my plants. Now for the fun part‚ I will perform an experiment or test‚ to either prove or disprove my theory or hypothesis. I will set up three groups of tomato plants
