Our website is a unique platform where students can share their papers in a matter of giving an example of the work to be done. If you find papers
matching your topic, you may use them only as an example of work. This is 100% legal. You may not submit downloaded papers as your own, that is cheating. Also you
should remember, that this work was alredy submitted once by a student who originally wrote it.
Predicted values of y given the regression equation y= 9.4349+0.095235x, replacing values for x and solving for y we get the predicted values of y to be. Heteros dacoity is a problem since there is a wider variability between the two variables in the scatter diagram. i.e. as the independent variable increases the gap.
The author states that in 2011, the Pearson correlation is zero meaning that the two variables, that is, borrowings and tax revenues are not correlated or they do not cause each other. In 2012, the Pearson correlation is 0.009853 meaning that there is some correlation between taxation and borrowing but it is very weak.

An ordinal scale is also known as a rank sale where variables are placed in a certain order while the difference between the variables is not known. Examples of its application are in Likert scales, such as measuring satisfaction, happiness, and discomfort among others. It can be best described by the median.
Are either of these two relationships significant? (2 points)
There is no strong relationship either between math achievement in 12th grade or reading achievement in 12th grade the coefficient
The graph created with Gapminder presents the dependence on CO2 emission and income per person. The data for all regions were used. The analysis of the presented data permits us to conclude that there is a significant positive correlation between the presented parameters. The higher the income per person in a particular country, the higher will be CO2 emissions.
However, due to pressure in terms of budget constraints and capacity to handle mentally ill patients, the concept of deinstitutionalization came into play. This required patients to be taken care outside state owned

Other factors that have been known to affect performance include family support, environment, food amount and quality, age, time of day of study, and stress levels. The present study hypothesized that the number of hours a student in grade 12 sleeps will ultimately affect their performance in math exams. For the study, data were collected from 100 Grade 12 students writing the same Math exam.
An Anova analysis was done with lifestyle as the dependent variable and social life as the independent variable. Anova analysis was done to determine if lifestyle and social life were statistically significant and if

Learning institutions admit new students into various academic programs. For purposes of planning, it is always important that the institutions understand the demographics which affect their student entrance demographics. Incidentally, there are lots of variables that dictate entrance. This paper assesses the role of various variables in the entrance.
The use of interviews ensures that there is no time delay between questions and the interviewer’s response; this synchronous communication answers that the answer of the interviewer is more spontaneous, without an extended reflection. Face-to-face interviews can also be recorded if the interviewees give permission, making it more accurate than writing notes.
lawed findings resulted to unscheduled drop in patients every day and corresponding occurrence of no-shows thus compromising the prevailing list that were mainly based on the patients scheduled on the past days.

The scientific method of study involves five elements, beginning with observations measurements which provide quantitative data. From the data, a hypothesis, which is a possible explanation for the observation made, is formulated. Experiments serve to test the formulated hypothesis, and based on the results, the hypothetical assumption is either affirmed or nullified.
Various tests for goodness of fit were also conducted to determine the appropriateness of the model. The results show that there is indeed a positive linear relation between the homicide
The above results can be confirmed from the linear graph shown below. We used a line graph because they are used to display data or information that changes
From theoretical conclusions, the screening effectiveness of the small apertures is inversely proportional to the square root of the number of individual apertures. This
n used instead of total value as the dependent variable since it is regarded as the average data on food, a measure of the food consumption of the population of a nation and it is particularly in comparison to other nations.
Looking at the table below (regression output table),
The hypothesis of the study was that the review of workers file and compensation had a significant impact on the decision outcomes of their cases. The null hypothesis would state that there was no such relationship among the two variables.
The independent variable was
Knowledge with regard to complaint behavior offers valuable insights into important areas, more particularly in the identification of common service problems. This allows improved service design/delivery, understanding perceived service quality by customers as well as in strategic planning. Arguably, it is important to encourage dissatisfied clients to complain to avoid the risks of losing clients.

Therefore, descriptive statistics refers to the type of statistical procedure whose key role is to describe a set of data provided. In addition, it uses numerical measures to present the features of a data set. On the other hand, inferential statistics are meant to study a sample of a population.
The author states that the regression forecast usually involves computation of confidence interval; and a forecast interval for an individual value is called a prediction interval. In most instances, prediction involves the process of extrapolation, which is a process of estimating, beyond the original observation range.
