Geometry is a primary subject of mathematics that studies object forms, sizes, and placements in space. Geometry has been studied for thousands of years and has played an essential role in scientific...
Introduction Examining the specifics of perception, particularly the ability to evaluate size and the related ability to perform a respective action, represents a peculiar area of study. Specifically, the correlation between the ability to assess the size of an object and take respective actions to grab or hit it represents...
The scientific revolution usually refers to the significant shifts in scientific thought that occurred in the 16th and 17th centuries. For centuries, the study has been dominated by Greek conceptions, which were replaced by new approaches during the scientific revolution. This change precipitated substantial developments in humanity’s history. Though it...
The selected research topic is the connection of the conscious perception and non-conscious perception with the person’s experience. The main assumption guiding the research on this topic is that people’s both conscious and non-conscious perception can be based on the previous experiences (Badgaiyan, 2012). Thus, having the certain experience associated...
Qualitative research is a growing field within philosophy. It is an area of philosophy focusing on empirical and experiential methods rather than traditional argumentative or logical methods. To better understand the scope, it is important to understand the criteria for evaluating the quality of qualitative research. Although some studies indicated...
For this week, it was proposed that two quantitative variables measured on an interval-ratio scale be selected in order to determine the extent to which their distribution conforms to normality. Normal should be understood as a distribution that is visually bell-shaped and symmetrical. From the theoretical point of view, such...
Introduction Lamarck’s idea about giraffe necks is that animals could pick up traits during their lifetime, through effort and struggle, then pass those traits on to their kids to give them a leg up. This theory is incorrect, as evolution doesn’t work that way. Species change slowly, over long periods,...
Introduction This report proposes a descriptive statistical analysis for the distributions of two variables measured on different scales from the GSS2018 set. The first variable used is the AGE measured on the quantitative (interval-ratio) scale, which characterizes the age of the respondent at the time of sample formation. AFTERLIF was...
It is essential to emphasize that the replication crisis refers to the argument that the results of many studies cannot be verified or reproduced, which leads scientists to assume that they are unreliable. I suppose that static bias is the reason for the biased attitude towards publications, which is causing...
Introduction Clustering is a popular data mining technique useable in determining the groups of similar objects in a dataset. Clustering is a critical technique for gaining insights into a dataset’s structure and identifying relationships between entities (Weissman et al., 2020). The report will evaluate the clusters and provide descriptive, meaningful...
The main objective of this lab work was to conduct a statistical study to determine growth distribution patterns for both the sample and the population. Such analysis is necessary in order to build a deeper understanding of distributions, make assumptions, and make data-driven decisions. Screenshot 1 demonstrates the results of...
Credibility is one of the main criteria in determining the suitability of scientific work for use in research. This phenomenon implies the trustworthiness and reliability of sources, which are determined by checking the facts given in them. To achieve this criterion, the authors of the research work must provide all...
Introduction This research essay aims to explore how mass and force affect the nature of an object’s motion. Thus, mass (m) and force (f) are independent variables, while the nature of motion is dependent. The measure of the nature of motion is its acceleration (a), that is, how fast an...
Introduction This paper is devoted to using descriptive statistical analysis to calculate probabilities in the context of consumer behavior. In particular, the initial data for the work is the distribution of respondents’ responses about specific characteristics and attributes of shopping areas in Springdale. The fundamental essence of such a study,...
Introduction Using statistical analysis to work with data is an essential part of obtaining results and conclusions based on facts. For the purposes of this paper, statistical tools are used to perform regression analysis, the purpose of which is to determine the nature of the relationship between quantitative variables. The...
Introduction Euler’s number, or the well-known constant, is one of the most relevant and important irrational numbers in mathematics and algebra. A natural number cannot represent a base number in an exponential function. This number is widely used in the world of mathematics. It is an irrational number, and scientists...
Introduction The development of students within the framework of academic disciplines is a difficult task for both the teacher and the students. The academic discipline, focused primarily on transferring the content of a specific scientific field, has a relatively limited supply of opportunities for developing personality qualities. Therefore, the main...
When making business decisions, a key need is quality control and risk assessment in order to predict the success of changes and minimize the potential damage to the company. A tool for such control can be statistical analysis, which is based on the use of data, so it prevents problems...
Introduction Conducting statistical analyses of data is a valuable practice for making decisions based on facts rather than experience or personal biases. Such data-driven decisions are much less biased and have a higher potential for achieving reliable results. In this report, statistical analysis is applied to a dataset containing time...
It is important to note that research designs can be divided into three distinct groups. These include quantitative studies, qualitative studies, and mixed-method studies, with the latter being the combination of the former two. The key features of quantitative research design are the use of numerical values as well as...
The concept of “radioactivity” was introduced by Marie Skłodowska-Curie. It is identical to the concept of radioactive decay. This process is accompanied by the emission of particles and electromagnetic radiation. The composition of the atomic nucleus is changed: its charge and mass number. Radioactivity is a phenomenon in which the...
Introduction Statistics have an essential place in modern-day healthcare, directly affecting its most significant components. In particular, the correct application of statistics contributes to the quality and safety of care and promotes beneficial health practices. Furthermore, statistics can point to more effective leadership practices, improving the care process. This paper...
Introduction The purpose of this project was to investigate the effect of exercise on the reduction of falls in adults compared to the absence of such exercise. Two variables of interest emerge from such a research topic at once, namely the frequency of falls in retirees, recorded as recording each...
