An Investigation into the Relationships between the Heights and
Weights of a Rangeof Studentsat Mayfield High
Aim
I aim to investigate the relationship between the heights and weights
of a range of students from different demographics at "Mayfield High".
Prediction
I.
I predict initially that the average male height will be greater than
the average female height. That is due to biology stating that males
are, on average, taller than females. Not only that, but studies have
shown that a percentage of females will have stopped growing by the
age of fifteen, whilst most males will continue to grow for far longer
than that. However, I predict that due to puberty and its occurrence
often being later than year 7, the male and female heights in year 7
will be much more similar. This I hope to prove via standard
deviation.
II.
Another prediction I make is that year 11 males will be taller and
heavier than year 7 males, as well as year 11 females being taller and
heavier than year 7 females. This I will try to prove by using both
mean and medians.
III.
One more hypothesis I will make is that the range of height and weight
of the year elevens will be greater than that of the year sevens. This
would be due to puberty having different levels of effect on different
subjects, and I can hopefully prove this using cumulative frequency
graphs, interquartile ranges and box plots in conjunction with one
another.
IV.
The simplest and probably most obvious of my predictions is that the
taller a sample is, the heavier they will be, ergo positive
correlation. This should be representable via the gradient of the line
of best fit being positive.
V.
Finally, anyone of a height of less than 0.8m or weight of less than
25kg should be considered an anomaly along with heights of more than
2.
This paper is a critique of an article written by McKinney and Jones (1993) entitled: “Effects of a Children’s Book and a Traditional Textbook on Fifth-grade Students’ Achievement and Attitudes toward Social Studies”. In their research the authors examined the effects of a children’s book and a traditional social studies textbook on knowledge acquisition and attitudes toward social studies and the textbook in a sample of 57 fifth-graders. It is the intention of the present paper to develop analytical discussion and the holistic interpretation of the McKinney and Jones’s quantitative study (1993).
Despite Russia being unstable during the 1860s due to political conflicts, class conflicts, and various revolutionary ideologies shaking up traditional customs, women were still constantly trapped in their own state of oppression. Women were faced with inequality everywhere - from their community, to even their own family. Compared to men, they were subordinated legally at every social level and weren’t allowed to participate in occupations outside of their domestic work. In What is to Be Done?, Nikolai Chernyshevsky implements much of the intelligentsia’s ideas for transforming the subordination of women. The novel centers on Vera Pavlovna, a woman who escapes a suffocating lifestyle and forced marriage, becomes an entrepreneur, and finds her own true love with the help of her new found independence. Chernyshevsky uses Vera’s journey as an example of how a woman is oppressed and how she is able to be liberated from that oppression.
Statistical analysis two independent sample tests compare the mean of the randomised case-control group. To find the significant difference between the two groups, data collections are mean value, so t test is the suitable test to compare the mean value of the two groups in normal distributed data (Menz, 2004). Result of the t test shows body mass index significant p value .005 less than .05 and the mean value of the BMI in case group greater than control group. The null hypothesis rejected, there is a significant difference in the two groups in body mass index.
The scientific method is the process by which scientists, collectively and over time, endeavor to construct an accurate (that is, reliable, consistent and non-arbitrary) representation of the world.
Statistics Project I have been given instructions to collect data for my GCSE statistics coursework and then to represent them by interpreting them using graphs and attributes, which I think influence the prices of a second hand car. Below is my coursework flowchart that will show the steps I will take to complete my coursework. FLOWCHART = ==
Heart rate is the different intervals of a heart beat and is influenced in the sino-atrial node of the heart by parasympathetic and sympathetic input (Meule, et al., 2012). Heart rate is influenced by a person’s physical conditions, and health (Thayer et al., 2010). Body weight, alcohol, and smoking all influence our heart rate (Thayer et al., 2010; Karason et al., 1999). Our whole lifestyle influences our heart rate. From when we wake up to when we go to sleep, each activity our day has influences whether our heart rate increases or decreases. A data collection worksheet was given to me in a class and I had to fill out a survey and a list of activities. Each student had their information entered into a spreadsheet where I had to then choose two activities. One activity has a higher heart rate than the other and that is what we need to find using the scientific method. I hypothesize that the heart rate before resting is significantly lower than the heart rate when one eats dinner. The steps used in the scientific method is materials and methods, and the results that conclude whether the hypothesis was correct or wrong.
As stated by Bartol and Bartol (2008), investigative psychology is the application of psychological research and principles to the investigation of criminal behavior (Bartol & Bartol, 2008). Investigative psychology is closely associated with criminal profiling, but there are other areas in which a forensic psychologist can participate in this particular subspecialty. An investigative psychologist maybe asked to perform a psychological autopsy, forensic hypnosis, or produce a geographical mapping. Psychological autopsies are generally performed in suspected suicide cases where the insurance company or family member questions the cause of death. Forensic hypnosis is an interview or interrogation method used by trained and credentialed professionals. Lastly, geographic mapping is a method of research “concerned with analyzing spatial patterns of crimes committed by numerous offenders over a period of time (Bartol & Bartol, 2008).” Geographic profiling is the analysis of a single serial offender’s geographic movement.
In statistics, a population is a collection of individuals, things, events, etc. The population is the topic that one wants to make inferences on, whereas a sample is a subset of the population that is being collected—to be studied. After the sample is studied in statistics, one draws an inference of the population. There are four general sampling methods used in statistics: representative sample, random sample and quasi-random sample, stratified and quota sample, convenience sample, and purposive sample. A representative sample should be unbiased and thus properly indicate a characteristic of the entire population. In a random sample nothing is biased; in other words, every individual, thing or event in the population has the same chance of being selected for the sample. Therefore, because of the randomness of the sampling, the selection of one item from the population in no way effects the selection of another item. A quasi-random sample is simply a number (nth), which is
This chapter taught me the importance of understanding statistical data and how to evaluate it with common sense. Almost everyday we are subjected to statistical data in newspapers and on TV. My usual reaction was to accept those statistics as being valid. Which I think is a fair assessment for most people. However, reading this chapter opens my eyes to the fact that statistical data can be very misleading. It shows how data can be skewed to support a certain group’s agenda. Although most statistical data presented may not seem to affect us personally in our daily lives, it can however have an impact. For example, statistics can influence the way people vote on certain issues.
17.7 million American women have been victims of attempted or completed rape (National Institute of Justice & Centers for Disease Control & Prevention, 1998; Rape, Abuse and Incest National Network [RAINN], 2009) and were three times more likely to suffer from depression (World Health Organization, 2002; RAINN, 2009). Statistics like these help psychologists know how common an incident is and to determine what may be wrong with their patient thus being able to treat them more efficiently. Statistics, like those above, apply every day in psychology, are extremely important, and analyzed in a specific way.

Statistics are necessary for scientific research because they allow the researchers to analyze empirical data needed to interpret the findings and draw conclusions based on the results of the research. According to Portney and Watkins (2009), all studies require a description of subjects and responses that are obtained through measuring central tendency, so all studies use descriptive statistics to present an appropriate use of statistical tests and the validity of data interpretation. Although descriptive statistics do not allow general conclusions and allow only limited interpretations, they are useful for understanding the study sample and establishing an appropriate framework for the further analysis in the study. Further analysis using appropriate statistical methods allows the researchers to establish correlations between independent and dependent variables, define possible outcomes, and identify areas of potential study in the future accurately. Statistics is important for researchers because it allows them to investigate and interpret the data more accurately, and researchers will notice patterns in the data that would be overlooked otherwise and result in inaccurate and possibly subjective conclusions (Portney & Watkins, 2009).
Whether or not people notice the importance of statistics, people is using them in their everyday life. Statistics have been more and more important for different cohorts of people from a farmer to an academician and a politician. For example, Cambodian famers produce an average of three tons or rice per hectare, about eighty per cent of Cambodian population is a farmer, at least two million people support party A, and so on. According to the University of Melbourne, statistics are about to make conclusive estimates about the present or to predict the future (The University of Melbourne, 2009). Because of their significance, statistics are used for different purposes. Statistics are not always trustable, yet they depend on their reliable factors such as sample, data collection methods and sources of data. This essay will discuss how people can use statistics to present facts or to delude others. Then, it will discuss some of the criteria for a reliable statistic interpretation.
