Deviation Critical Thinkings Samples For Students

Gulf Real Estate Properties

Introduction:
The following is a discussion of the various characteristics of Gulf View condominiums (GVC) and non- Gulf View condominiums (Non-GVC). Various descriptive statistics including the mean and standard deviation are explored. An analysis of differences using two-sample t test is undertaken to determine differences in selling prices and days to sell. The confidence intervals are determined and the sample size required to achieve desired margin of errors is determined. GVC refers to Gulf View condominiums while non-GVC refers to non-Gulf View condominiums.

Gulf Real Estate Properties characteristics:

Descriptive statistics for GVC indicate that the mean list price is 474, the mean sale price ...

Histograms are used to show distributions of variables while bar charts are used to compare variables. Histograms plot quantitative data with ranges of the data grouped into bins or intervals while bar charts plot categorical data.

Whereas an example of a bar graph data would show what percentage of people with a certain hair type have a certain eye color.

Introduction

This paper reports the results of hypothesis test conducted on eleven variables captured in the Springdale community shopping survey. The null hypothesis was rejected in nine out of the eleven variables analyzed.

Analysis

- Mean and standard deviation

Springdale Mall

Mean = 3.813
Standard deviation = 1.064

Downtown

Mean = 3.407
Standard deviation = 1.124

West Mall

= 3.287
Standard deviation = 1.183

Article Critique
The paper presents a statistical analysis of Brisbois, Kock, Watanabe, Mirhosseini, Lamoureux, Chasen, MacDonald, Baracos, and Wisner (2011) article "delta-9 tetrahydrocannabinol may palliate altered chemosensory perception in cancer patients: results of a randomized, double blind, placebo controlled pilot trial". The research aimed at determining whether Tetrahydrocannabinol (THC) therapy on cancer patients can improve smell and taste perception. This is well outlined in the article. The research was triggered by the effect of anorexia and weight loss on patients with advanced cancer; this results to functional loss, low quality life and low survival chances. Therefore, the research investigated the ...

Abstract

This report contains the results of point estimate and confidence interval analysis for five variables obtained from the results of Springdale community shopping activities survey. The survey was conducted to determine the strengths and weaknesses of three shopping mall areas; Springdale Mall, Downtown Area and West Mall. The variables analyzed are general attitude towards Springdale, Downtown and West malls, and gender and marital status of the respondents. The maximum likely error for mean general attitude ranged from 170 to 0.189. On the other hand, maximum likely error for gender and marital was 0.003.

Introduction

Point estimation is a statistical technique used ...

SPSS can be used to obtain various descriptive statistics such as frequencies, mode, mean, minimum, maximum, standard deviation, kurtosis, skewedness, interquartile range, and range for each variable. Various commands are used to execute the processes. The procedure I used to get the frequencies is shown below:
- On the main menu bar click ‘Analyze’.
- Click ‘Frequencies’ and a window with a list of all variables pops up.
- Click the ‘Format’ button, and set the output format.
- Click the ‘OK’ button.
Descriptives command computed mean, standard deviation, minimum, and maximum for numeric variables. The ...

Q2. A proportion is the mean of a variable that is 1 when the individual has a characteristic and 0 otherwise. The standard deviation of any variable is given by:

The mean of n of these observations give the sample proportion. The standard error of the proportion is expressed as the SD of one of them divided by the square root of the sample size or by the formula:
Standard error of the mean is the estimation of the variability that exists between sample means that are obtained from picking multiple samples from same population. The variability between the ...

- Construct a relative frequency histogram for the chest circumference data, using classes based on a single value.
Looking at the table we first have to get the total frequency by summing the values in that specific column. The table is filled according to the following procedure. You can check out the excel file attached alongside that show numerical workings.
Arrange the value in the order presented and then multiply each frequency and chest size per row to get the product of frequency and chess size. When you add the entire column of the results and divide by the ...

Although both the terms are quite similar and are used interchangeably with one another, corruption and official deviance in policing are quite different. In a nutshell, it can be said that corruption only forms one of the aspects of official deviance in policing, whereas deviance is highly related to the ethical side of official duties. Corruption is a matter of self-interest and morals of the individual who is concerned about a certain job.
Police deviation can be distinguished as the behavior that the police adopt when they hold a position of authority over the rest of the people. This ...

Using the t test to determine the statistical difference in the number of days it takes to start a business between emerging and developed markets

Learning Institution
Introduction
According to World Bank (2015), the time required to start a business is defined as the number of days needed to legally operate a business in a given jurisdiction, usually a country. This study was conducted to find out if there were statistically significant differences in the average number of days it takes to start a business between developed markets and emerging markets. Time and cost are deemed important due to ...

Question 1

Steps of hypothesis testing
Here, the researcher identifies his population of interest, value of the parameter which in this case is hypothesized and the parameter of the variable he intends to investigate. This variable can be categorical, continuous or discrete. The variable will define which statistical test will be suitable on the collected data set.
- Specify alternative and null hypotheses.
Here, the researcher states his research question in terms of alternative hypotheses or null hypotheses. Null hypotheses is a positive while alternative hypotheses is negative.
It also involves selecting a significance level and evaluate the assumptions ...

Personality congruence can be well explained when there components of an individual: real, perceived and ideal self fits together. It’s a state of being healthy and it assists people to progress positively in self-actualization. In a partnership, it’s a state of coming together in an agreement and living a happy life. Personality congruence increases the longevity of couples in a relationship since it bonds together their similarities and does way with the differences (John, Donahue & Kentle 1991). A number of researches are being conducted to show the relationship between partnership longevity and personality congruence in couples. One of the most prominent studies ...

Modern option pricing models are usually regarded as some of the most complex mathematical models in applied finance. However, these models have enabled financial analysts and savvy investors to calculate the value of stock options with alarming accuracy. Most of the modern option pricing models employed in determining the value of stock options are rooted in the Black and Scholes model which was developed by Myron Scholes and Fisher Black. The Black and Scholes model was first published in 1973 in the Journal of Political Economy in a paper titled “The Pricing of Options and Corporate Liabilities”. Although the Black ...
