The main conclusion of the study was that residency significantly

affected the aggressiveness in house crickets. A limitation of the present study could

come from a subconscious labeling of the bigger cricket as the resident to acquire an expected result.

This would allow the resident to have a clear advantage in a confrontation, and it would also intimidate

the intruder via physical assessment. To improve the experiment, use fresh crickets during the experiment in order to avoid exhaustion, and faulty subjects.

The results received from the Chi-square goodness of fit test were x^2=30.368, degree of freedoms was 1 degree, the p value was less then .0001, and n was equivalent to 370.

The main conclusion is the aggression in crickets was not random but infact lent itself to residents being more aggressive then intruders.

The limitations in the current study was the variation is sizes as well as the over use of the crickets.

Fix the limitations of the prior study and the results well be better and more accurate.

(x^2=30.368, df=1, p- value is less than .001, n=370).

Since p-value is less than alpha (.05) we reject the null hypothesis and support the alternative hypothesis.

Expected value for both the resident and the intruder is 185. The total number of wins for the residents in the sample was 238, while the number of wins for the intruders was 132.

The results from the chi square test were 30.368, which concludes that the resident crickets are more likely to win more fights due to higher motivation and aggression.

Limitations would include the liveliness of the crickets and whether there was still food in the boxes, as well as size of the crickets.

Main conclusion is that there is a correlation between the residency of the crickets and the number of wins displayed.

Since the p-value is extremely small, the results are extremely significant. We can therefore reject the null hypothesis and say that the results support the alternative hypothesis that residency does, in fact, affect the motivation of the male crickets in aggressive encounters.

The null hypothesis is rejected. We can conclude that that the observed wins will not be equal to that expected by chance.

A limitations of this study is that the population sample was not big enough to generalize to all house crickets. Also, the crickets were used more than once thus their behavior could have been affected if they had accustomed to the situation presented in the experiment. The crickets could have been agitated from constantly being put in the same situation and that could have caused them to be more aggressive than usual.

The next step would be to use a bigger sample size.
