For this assignment on collecting and analyzing naturalistic data I collected data on what percent of students held open the door entering and exiting Beatty hall. There are four categories that student can fall into during this study students that: don’t hold open the door, wait and hold open the door, automatically hold open the door, and don’t have anyone to hold the door open for. The people that automatically hold open the door are passing the door to someone immediately behind them. I hypothesize that 20% of students to enter Beatty will wait and hold the door for the next person and that an additional 30% will automatically being holding the door for the next person due to proximity. The remaining 50% will be 30% of students that don’t hold the door and 20% where there is nobody around to hold the door for. I estimated these hypothesized amounts based my experience of going in and out of Beatty over the last 4 years. Figure 1 is a pie chart providing a visual of the hypothesized percent of people holding the …show more content…
door. This research design experiment would be classified as descriptive research because it analyzes the behavior of individuals. This type of descriptive research is also known as naturalistic observation which is “research based on the observation of everyday event.” (stangor 2.2) I spent 20 minutes sitting inside Beatty analyzing the doors to see who would hold open the door and who would let the door drop entering and exiting the building.
It is important to note I am considering a person who is within 6 steps of the door clearly going to enter the building as the distance of an opportunity to hold open the door. During this 20 minutes 149 people entered or exited the building. Of those 149 people 31 people did not have anyone to hold open the door for leaving 118 people that had the ability to hold the door for the next person. Of the 118 people 94 people held open the door while 24 people let the door close on the next person. Within those 94 people that held open the door 67 people held the door for someone who was a step behind them which still counts as holding the door but not as substantial as the remaining 27 people who decided to wait and hold the door. A pie chart breaking down the statistics can be seen in figure
2. Comparing the hypothesized and experimental percentage of door holding in figure 1 and figure 2 it can be seen the data varied what from what was guessed to occur. The percent of people who were flowing through the door was greater then estimated causing the automatic door holding amount to be higher in experimental. The amount of people that didn’t have anyone to hold the door for and that did not hold open the door varied only slightly from the hypothesized amount. The amount of people who did not hold the door was significantly less then the percent estimated prior to the experiment taking place.
The final chapter of this book encourages people to be critical when taking in statistics. Someone taking a critical approach to statistics tries assessing statistics by asking questions and researching the origins of a statistic when that information is not provided. The book ends by encouraging readers to know the limitations of statistics and understand how statistics are
The Importance of a Painted Door. The title is what puts the story in motion. It tells and carries the weight of a piece of work, the title The Painted Door is a guide as it connects physically and emotionally to its short story. The story revolves around the door that is being painted to avoid the modernist theme of loneliness, desperation, and temptation of a new life at any cost. The Painted Door represents the choice of a new life, even if it's not the intent at the moment.
Each of the four central characters, Helen, James, Gerry, and Lydia, can be recognized by individual and distinct traits that differentiate them from each other. The protagonist, Helen, is a hardworking woman with relatively low self-confidence who is often skeptical of people and good news that comes into her life. After losing her job, Helen works many part-time jobs in order to make ends meet and, in a parallel time line, starts up her own PR company. James is a nice, successful man who tries very hard to cheer up Helen and also has his own company. However, James isn’t entirely honest with Helen, because he hides the fact that he is married to Claudia. Gerry, in contrast to James, can be characterized as a fickle man who is both dependent on Helen for support and deceitful. Gerry’s inability to choose between Helen and Lydia, persistent lying to Helen and even Russell, and lack of income are all factors that contribute to his characterization. Lydia is the polar opposite of Helen. She is an aggressive and conniving woman who is emotionally dependent on Gerry. Her constant phone calls, plots to inform Helen of the affair, and stalker tendencies all add to her “live-wire” status. While we can become aligned with each of these characters, their actions all ultimately lead us to only become allied with Helen and James.
2. The probability that a house in the Glengarry Neighbourhood has a pHQ2011 exterior housing quality percentage within the normal range which is greater than or equal to (-10%) is 0.368% which is about 37%. Therefore more than one third lands in -10% to 10%. Correspondingly, a pHQ2011 overall exterior housing quality percentage below normal which is less than normal range is 0.454, which is also 45%, less than one half. Therefore if we know that one third score above and less than one half scored below, we can infer that about 18% is in the normal range.
When it comes to opening a door there are many ways you can do it. You pull a handle, turn a knob, push it forwards, press a button or simply stand in front of it. It’s strange to think that the door, an object we are all familiar with hasn’t existed forever. The door opening mechanism has been around for amount of time, as the door knob was invented much later than the door itself.

It was a great summer afternoon when Bernard was playing lacrosse with his best friend and his neighbor. At three o'clock they all went home. Since they were in Bernards backyard he didn’t have to walk much. When he got home he went to his fridge and got a Coke. Bernard heard a small creak, then he looked at the door. The doorknob turned Bernard was completely sure of it. His heart was pounding so fast he thought he was having a heart attack. The floor started cracking on the other side of the door. He wanted to run, but since he wasn’t very fast he opened the door. He looked up, down, right, and left. He saw nothing. Then he heard the door creak behind him. He turned around nothing again. He heard footsteps running and he saw a shadow go behind the stairs. He yelled, “Who are you?” No response so he yelled again. Still nothing. He looked around and as he was looking the intruder started running. Bernard started running. He told to the person intruding, “you better stop or I’m going to call the police!” When the intruder didn’t stop Bernard called the Police and said, “please send ...
Most people travel to school by bus and travel at least 10 miles. The amounts of people who travel by bus from my random samples are 25 pupils all together. The amount of pupils who travel to school by car is 2 pupils and the amount of pupils who get to school by walking is 3 pupils.
This section will introduce ideas around the politics of migration and open borders, in order to lead us into my critical analysis of migration, the brain drain, and what policies can be created for the best possible outcome. As previously mentioned, brain drain is the only possible clause to which immigration can be restricted. However, only if it causes deleterious effects to the poor nation is it acceptable as a restrictive cause. Nevertheless, restrictive immigration goes against fundamental basic human liberties in which a person has the right to leave one country and go to another. I return to develop the libertarian aspects that advocate for open borders based on Carens understanding of Nozick’s work. Nozick
First, I enjoy people. That is why I like an "open door" policy. People must first know that you care before they will open up. I remember a former lunchroom employee who dropped by the Central Office one day. The receptionist informed me of her and stated “She has asked for help from the last two Superintendents but she will not listen.” I asked the receptionist to inform her that I would be with her in just a few minutes. I then pulled her personnel file. She had worked in a lunchroom where she injured her knee. According to the court settlement, her attorney encouraged her to resign and to accept a $30,000.00 settlement. She did and he took half. I went out to the waiting room and asked the lady to come into my office. I sat
Fifteen students came into the café, whereas only one individual identifying as anything other than a student came in. I considered recording gender for analysis as well, but after some further thought, I’ve decided that any data I collected on that could be considered incorrect due to gender non-conformance being more common in this area than in most places – at least one person entered the café that I actually know, and they are a non-conforming individual. Regardless of their demographic, people came in with usually one of two purposes: to get their coffee/food and leave, or to go upstairs to enjoy their food and do work individually. Only two groups broke this trend, one stayed downstairs to study, and the other went upstairs for what seemed to be a small date – I had only gone upstairs for a moment on consideration that maybe I should put in some time up there, but decided that it was a bad idea because it already kind of seemed like I was following these people that were probably on a date. I’m not particularly
One of my friend was looking for someone to make a small project as to convince his supervisor not to change the rule. I saw it as a perfect opportunity to use my ability, and I volunteer to help him. In his case, an employee with review score of 90% will receive bonus money for each cycle. Regardless, due to the change of rule, employee currently needs to have the score of 92% so as to receive the bonus. I used the survey data he provided to analyze the impact of the new proposing rule. I use the normal distribution to approximate the binomial distribution. I was able to find the probability of not getting a bonus for both the threshold of 90% score and 92% score. The result was unpredictable. With 90% score of threshold, employee only have 42.8% of chance not getting the bonus whereas 92% score have a 72.6% of not getting the bonus. Eventually, with the project I provide, my friend was able to convince his supervisor not to propose the rule. Overall, it was motivating to involve into the surface of statistics, and I understand that the usage of statistics can totally influence our daily life. Although it is just a small project, being able to contribute part of our community make me proud of
percentage of accompanying persons that yield to the various types of influence attempts made by the kids at the store.
The house was still. A pin could have dropped and we would of heard it.
