It is the core of whole research design. In the article, we use the “Research Onion” as symbolic word to describe relation between the core of research onion and outer layers on research onion. The situation (context) and limits within which data collection techniques and analysis procedures are selected depends on researcher’s understandings and decisions […]

The designated classification of design encompasses multiple intentionally formed groups, consistent measurements, and random assignment. It is considered the most precise form of experimental methodology. This approach utilizes statistical analysis to mathematically prove or disprove a hypothesis. To fulfill the requirements of a true experimental design, the sample groups must be randomly assigned, a viable […]

Different types of scales, including numeric scales, semantic scales, and graphical scales, are used in marketing research. It is crucial for marketing researchers to have a comprehensive understanding of all scaling measurements to gain insights into markets. Marketing research texts typically outline the four levels of measurement: nominal, ordinal, interval, and ratio. Nominal scales are […]

The Vintage Restaurant is on Captiva Island, a resort community near Fort Myers, Florida. The restaurant, which is owned and operated by Karen Payne, has just completed its third year of operation. During that time, Karen has sought to establish a reputation for the restaurant as a high-quality dining establishment that specializes in fresh seafood. […]

Introduction: Cryptography involves writing messages in code or cipher to secure the content of a text. The encrypted message can only be deciphered using the key used for encoding. It does not hide the existence of the message, but conceals its content [1]. On the other hand, cryptanalysis aims to retrieve the plaintext from a […]

Abstract: In classical sparse representation based classification (SRC) and weighted SRC (WSRC) algorithms, the test samples are sparely represented by all training samples. They emphasize the sparsity of the coding coefficients but without considering the local structure of the input data. Although the more training samples, the better the sparse representation, it is time consuming […]

Curvelet-based bayesian estimator for speckle suppression in ultrasound imaging Ultrasound images are inherently affected by speckle noise, and thus reducing this noise is crucial for successful interpretation. Bayesian estimation is a powerful technique used to remove speckle noise in images. This paper presents a new despeckling scheme for ultrasound images using a Bayesian-based approach. The […]

Turnover survey procedure This study will adapt survey research design. Wyse (2012) acknowledges survey distributions will form a flexible yet convenient mode of data collection on a small scale level. Since the respondents of the research are located in one place. Hence, using survey questionnaires that are physically issued to respondents will serve crucial in […]

Descriptive Statistics Analysis The descriptive statistics conducted in this study are displayed in Table 1 . From the table, it is evident that the average client identification is 3.16, which is below the midpoint of the scale (p<0.001) and is statistically significant. The value of 0.675 standard deviations suggests a substantial variation in the identification […]

The first step in building our simulation model was to confirm whether or not a normal distribution was in fact reasonable for the unknown demand of Egress ski jackets in the coming year. To do this we input Egress’ estimated demands into Best Fit. After analyzing the output (Exhibit 1 and 2) we see that […]

In this part of my coursework I am helping a local corner shop in Harlesden to solve its information technology problem as they are struggling to work manually with all there float (foods and drinks record. ) My aim is improve their problem by introducing information technology to make it more accessible and easier for […]

Idaho: ID is a distinct variable type with a nominal degree of measurement. It provides an identification number for the entire dataset. Age: Age represents the continuous variable type that measures the age of the individuals in the sample. It is measured on a ratio scale. Gender: Gender categorizes the population into males and females. […]

The intent of this research is to find when it is more desirable to come close a distinct distribution with a normal distribution. Particularly, it is more convenient to replace the binomial distribution with the normal when certain conditions are met. Remember, though, that the binomial distribution is distinct, while the normal distribution is uninterrupted. […]

The uses of probability theory with Decision Making are key tools for corporations to made key decisions on new markets and investments. CoffeTime Corporation used Key Tools such as Bayes Theorem and comparisons of probabilities of random and continuous variables in order to access the best approach for the initial phase of the operations for […]

The objective is to determine the likelihood of selecting a measurement between 19 and 31 from a normally distributed population with an average of 25 and a variance of 9. In order to accomplish this, we must convert the values 19 and 31 into their respective z values using the transformation formula for X to […]

Instructions This is a GROUP assignment. Each student must be part of a group of 4 or 5 students selected by the lecturer. Solutions from each group must be submitted by 19 April 2013. Special Distributions Concept of probability (3%) Explain why the distribution B(n,p) can be approximated by a Poisson distribution with parameter λ […]

There are many ways of comparing the birth rates of countries compared to other countries, and one way may be to look at the life expectancies of the countries. I believe that there is will be a correlation between the two variables: The average birth rate of a country per 1,000 and the Life expectancy […]

Assumptions Production Rate 1,000 dozen pies every 20 minutes Monthly Production – 60,000 dozen pies Yearly production – 720,000 dozen pies Thrift store demand – 240 dozens per month Thrift store storage max – 1000 dozen pies Rejected batches are first sold at the Thrift Store and excess donated to charity The threat of situation […]

According to Hamdy Taha’s 1998 book (p. 607), queues are systems that require waiting in line, and studying them helps determine the efficiency of waiting lines by considering factors like queue length and wait times. Identifying the suitable service for a specific situation or facility is the main objective of this research. According to Render […]

Dates The data used is ETG cost data from a top national health insurance company. It includes 33 million observations from 9 million claimants. Each observation represents the annual total cost per claimant for each ETG. Policyholders without claim costs for specific ETGs are not included in the dataset. There are a total of 347 […]
