# Handling Data Mayfield High - Research Paper Example

Summary
Based on the provided data for students at Mayfield High School in grades 7 to 11, I chose to investigate whether there is a relationship between height and weight of students. In order to complete the task, I started with analysis of a random sample of data for 30 boys and 30 girls across all five grades.

## Extract of sample "Handling Data Mayfield High"

Download file to see previous pages To test the hypothesis that there is a positive correlation between the height and the weight and "the taller a person the more they weigh", I used scatter plots and cumulative frequency diagrams. The trends and positive slope of the best fit line support the hypothesis. For verification, I have used two additional sets of data, one for people in the 7th grade and one for the 11th grade. Although more cluttered, the data for these two additional sets also supports the hypothesis.
I could use the entire table, but it is so large that I could very quickly make mistakes. So, in order to begin, I chose to collect a random sample of data. I decided to collect samples of size of 30 for boys and girls because it is large enough to ensure that the sample is representative of the population. At the same time, sample size of 30 is easy to work with and would allow me to avoid mistakes in calculations.
To assure randomness of the sample, I used Excel function RAN ( ) to assign each entry row a random number from 0 to 1. Then I sorted the rows according to their random numbers and chose the first 30 entries. The obtained samples are in the table below:
But this is not enough. I don't see any trends or anything in this list. So I need to put it in a chart that will tell me how many people fall into each group. I'll make each group cover 1/10 of a metre, or 10 kg.

Now I can see that there are no girls who weigh more than 75 kg or who are taller than 1.9 m. I can also see that boys tend to be taller than girls. But if I can turn this into a picture, I can then compare the boys' data with the girls' data.
Heights of Boys and Girls
And to compare boys and girls, I can put them both on the same graph.
It looks like more boys are taller than girls, which I think is normal. I can do the same for weight.
Weight of Boys and Girls
And to compare the weights of boys and girls:
From the graph above it seem that boys' weight is more spread out. Girls seem to be closer together, and don't seem to ...Download file to see next pagesRead More

### Handling devices

...?Handling devices Roller conveyor: One of the materials handling devices found in my organization belongs to the category of transport, i.e. roller conveyor. It is used to shift goods from one place to another. The material may be moved from one workplace to another or from a dock to another. The benefit of using the roller conveyor is that no matter how heavy the load may be, it gets moved with minimal inconvenience and time as it has to be moved mechanically by rollers. No manual work is involved in it. The smallest thing to be transported has to be broad enough to cover the width of at least three rollers in order to be moved (MHE Taxonomy, 1999). I would like to reduce the diameter of the rollers so...

### Information Handling

...﻿Information Handling There are key terms used in sampling. They include: - (i) Population – This refers to the set of units under study. The study should not go beyond the population i.e. outside the population. (Abell, & Oxbrow, 2001.p. 200). (ii) Sample - This refers to a part of the population. It is usually hard to study the population as a whole hence the use of sample (Grimshaw, 2003p.86). Basically a sample should reflect the population (Taylor, Farrell, 1994p. 118). There are ways in which a stratified sample can reflect a population. For example in our case of Tundra.com the stratified sample of size 300 can reflect the population (David P. Best (1996.p166p). This is possible through ways such...

### Handling Conflict

...LEADERSHIP STRATEGY Emotions and moods could have real consequences for getting work done. When the leader shows mild anxiety, this usually acts as a signal that there is need to focus more attention on something. A sudden flood of anger shifts the attention of the leader from the more important things. For example, if a leader hears that one of the senior executive has engaged in sexual harassment, he ends up directing all his energy from the normal concerns such as improving the normal efforts to eliminate harassment (Goleman, Boyatzis, & McKee, 2013). Several discoveries have been made in an attempt to improve leadership strategies. It has been noted that the more optimism on the top management team leads to cooperation among... STRATEGY...
