It was assumed all other strands not on the floor had been used in nest construction. Data from the three colonies were pooled and an X 2 goodness-of-fit test was used to determine whether the number of strands of each color used in nest construction different from an expected ratio of which would indicate no preference.

Description of methods includes assumptions made and type of analysis to be performed on the data. More green material was removed by the finches than red, more red than black and more black than orange. The author interprets the data for the reader in text form.
The Scientific Method and Psychology Research
The results from these experiments suggest that zebra finches do in fact have color preferences with regard to nesting material. These results are similar to those of Collias and Collias who showed that weaver birds preferred green nesting material. Results are compared to those from other studies.
It is possible that zebra finches prefer green material to red, black and orange because green is more similar to the color of the grasses commonly used as nesting material in their natural environment. This interpretation, however, does not explain the preference for red and black materials over orange.
Alternatively, it is possible that the strong preference shown for green material may be a result of imprinting on the color of the nests they grew up in. It has been shown, for example, that parental plumage color has a strong effect on mate selection in male but not female zebra finches Walter, All of the birds used in this study have been exposed to grass, green embroidery floss and white dog fur in nests.
If as suggested by Morris males collect most of the nesting material, imprinting could have a strong effect on the numbers of colored strands collected in this study. This hypothesis could be tested by raising zebra finches in nests containing different colors of nesting materials and testing them in adulthood for preference in nest material color. When setting up this experiment, it was noted that zebra finches seem particularly apprehensive about new objects placed in the colony.
It is also possible, therefore, that the preference for green nest material was simply due to its familiarity. Alternative hypotheses are also provided, and evidence from literature is given in support of the alternate hypothesis. Burley, N.

So how does a researcher decide what the results of a study mean? When results are said to be statistically significant, it means that it is unlikely that these results are due to chance. Based on these observations, researchers must then determine what the results mean. In some cases, an experiment will support a hypothesis, but in other cases, it will fail to support the hypothesis.healthinsure.website/wp-includes/romopides/visto-de-namoro-brasil.php

So what happens if the results of a psychology experiment do not support the researcher's hypothesis? Does this mean that the study was worthless? Just because the findings fail to support the hypothesis does not mean that the research is not useful or informative. In fact, such research plays an important role in helping scientists develop new questions and hypotheses to explore in the future. After conclusions have been drawn, the next step is to share the results with the rest of the scientific community.

This is an important part of the process because it contributes to the overall knowledge base and can help other scientists find new research avenues to explore. The final step in a psychology study is to report the findings. This is often done by writing up a description of the study and publishing the article in an academic or professional journal. In these articles, researchers:. Why is such a detailed record of a psychological study so important? By clearly explaining the steps and procedures used throughout the study, other researchers can then replicate the results.
The editorial process employed by academic and professional journals ensures that each article that is submitted undergoes a thorough peer review, which helps ensure that the study is scientifically sound. Once published, the study becomes another piece of the existing puzzle of our knowledge base on that topic. Ever wonder what your personality type means?
