8. Compare the mean for the heights of males and the mean for the heights of females in these data. Compare the values and explain what can be concluded based on the numbers.…
My group examined the correlation between standing height and leg length in centimeters for ten of our classmates. Our supposition was that there would be a direct relationship and similarity between standing height in centimeters and leg length in centimeters. Therefore, our hypothesis was, if leg length increases, then standing height will also increase.…

The Multimeter will be turned on and set to measure resistance (Ohms), and 2 wires will be placed in the appropriate holes in the Multimeter.…
1.) How did you test your hypothesis? When testing your hypothesis, which variables did you change in order to compare your growth results.…
Data is only as good as the collection and maintenance mechanisms are. Unfortunately, concerns for the validity of the data arose when looking at the experience level of the data collectors, response bias, and using the coin-toss (50/50) method for obtaining direction to travel to each cluster of responses identified in the survey. Ensure both the scientific approach and procedures are well within standard, but also ensure that the common sense factor is considered as well. Sometimes the sensible approach can be lost in the algorithms and…
If my p-value was considered (>0.05) then my evidence would be weak meaning that the type of shoes worn by the…
I collected the data from twenty males all from the Montclair State University. The results for this study could be beneficial for homeless shelters and clothe drives; for example men could come in give their height and receive a care package of goods including a pair of shoes that suit their height and size perfectly. Individuals were asked to write down (roughly) their height, along with their shoe size. The reason I say rough is because all information is subject to biased because most heights were rough estimates, along with shoe size, which truly doesn’t measure the size of ones, foot. Because with shoe size you have to consider variables such as the different shapes of the human foot; so in order to make my data as accurate as I could make it I restricted my study to males, because males and females have different shoe scales. For future studies the sources of error mentioned above should be addressed, but when taking all this information into consideration my data still resulted in a positive linear trend.…

The importance of inference and interpretation in research is that it helps the researchers to understand their research better. Inferences are conclusions or guesses that will aid the researchers on what questions need to be answered or what facts need more evidence. Interpretation, on the other hand, is also important for the researchers to widen their topic. Interpretation of data gives a more detailed definition of statements made by the researchers. While inferences broaden the investigation of the answer, the interpretation backs up the validity of the answer. An example of this is our own research, Subli. We made inferences about the Subli’s dance movements and costumes. After researching and interviewing, we came up with the answer. After getting the answers,…
4. The heights of 10 males of a given locality are found to be 70, 67, 62, 68,61, 68, 70, 64, 64, 66 inches. Is it reasonable to believe that the average height is greater than 64 inches? Test at 5% significance level, assuming that for 9 degrees of freedom P(t > 1.83) = 0.05.…
Therefore to prove our research we provided 50 copies of questionnaires to be answered by two students (one girl and one boy) per section from 7th grade to 4th years. On the date February 6, 2013 Lunch break we started to float our questionnaires starting from the 3rd year level then going down to the 2nd and 1st year level and ending with the 4th year level. After collecting all the floated questionnaires we started to gather data using books, magazines and newspapers from the library. At home we used the internet to…
