Comparison of math standards: Using graphs in Grade 5 to solve problems
The Texas TEKS and the Puerto Rico Core Standards pertaining to understanding and applying the information presented through graphs were compared. While some of the student expectations are similar across each standard, the Texas TEKS require students to use graphs in more complex situations such as graphing a pattern when given an equation and solving two-step problems using data from a graph.

    Following the correct guidelines for significant figures is crucial in reporting accurate data that is reflective of the accuracy of the means used to collect it. It follows that the answer to any calculation can be no more nor any less precise than the least precise piece of data involved in the calculation. In this course, we will follow a set of rules meant to a) provide consistency to our significant figures and rounding and b) provide answers that agree, in accuracy and precision, with our measured data. These rules allow us to skip complex, although more accurate, data analysis, and provide us with a workable, functional, and accurate enough method for our purposes.…

    Five frequency (f) tables will be constructed for univariate analysis. Standard deviation (SD) will be calculated for treatment outcomes. The standard deviation will allow the researcher to examine how much the individual values of the tables differ from the mean and other values (Royse, 2010). Percentage (%) will be calculated for all nominal variables to help visual the data through historgrams. Mean (M) will be calculated for age and education level which will help determine the average of each nominal variable.…

    Effectiveness of an e-learning tool for education on pressure ulcer evaluation Pressure ulcers also known as bedsores are considered one of the greatest challenges that nurses face with their daily regimen according to (Demarre et al. 2011, Revello & Fields 2012). Pressure ulcers are caused by a patient not being repositioned frequently, poor nutrition, poor skin care as well as many chronic diseases such as Diabetes Mellitus (Mayo Clinic, 1998). A trial test was conducted by undergraduate nursing students to determine if the e-learning software is more effective than the traditional lecture style class (Biggs & Tang 2011). At present, the traditional lecture style class is focused on looking at different types of pressure ulcers and their different wound stages on photograph. This theoretical training is usually accompanied by clinical practice in which the students can observe and treat wounds in a real clinical context (Dobbin 2001, Gulpinar &…

In research study sampling theory is necessary, because it is a section of statistics, which included population, target population, sampling eligibility criteria, methods, plan, assessable population, elements, representatives. The sampling theory is not complete with selection of observation of population. That will start with the random sample, the use of probability theory with population limitations Then evaluate the data from the random sample and develop conclusions from the investigation.

    Summary Jorge R. Sanchez, in this article “Economic Benefits of a Community College Education: Issues of Accountability and Performance Measures” focuses on a specific outcome: the economic benefits of a community college education. The importance of a two-year education is commonly overlooked. The way the government looks at wages directly correlated with higher education is sub par and needs to be enhanced. In 20 states, the primary method for judging the post-college earnings of students has been to use information maintained by the state’s department of labor unemployment insurance wage record files.…

    In terms of primary data, questionnaires and structured interviews were conducted to obtain quantitative and qualitative data. With questionnaires, I chose to use the simple random sampling method when distributing my questionnaires to obtain the most accurate, valid and unbiased data. Of the 30 questionnaires distributed 30 were obtained. At particular pre-selected time intervals (during school) I distributed questionnaires in sets of three to individuals ranging from twelve years old to the individuals seventeen years old and over.…

    Applying ROI as a Further Step in Kirkpatrick Model: The Process If Phillip’s ROI model is used as the evaluation tool for a program, it will calculate monetary cost and non-financial returns at all levels of the program. On the other hand, if the ROI aspect of Phillip’s model is used as a further step to the Kirkpatrick’s model then evaluators will garner all the data from Kirkpatrick’s level four, and translate them in fiscal value or hard data (quantity, quality, cost, time). The ROI will then be calculated based on all the data gathered. Irrespective of the way in which ROI is applied, it involves a process which is used as a guiding principle to evaluate a training program.…

    “Scientific research is increasingly recognized as a vital catalyst and important index for national development. In many countries, it is scientific research, rather than rich natural resources that have a direct impact on economy and development”. (Samir Al-Adawi, 2015) One must not take for granted that when an article or journal is published, the statistical methods that have been used are correct. “Unscrupulous medical research not only halts the progress of medical knowledge, but also creates unanticipated consequences. For example, this has vividly occurred in the case of concurrent data and the association between autism and immunization.…

    Baptism is a ceremonial immersion in water, or application of water, as an initiatory rite or sacrament of the Christian church. It symbolises the covenant between God and mankind to save all of mankind from eternal damnation if they believe Jesus Christ to be their Saviour. It is an important part of the Catholic journey, as it is considered to be the initiation into the Catholic church; John 3:5; Jesus answered, "Very truly, I tell you, no one can enter the kingdom of God without being born of water and Spirit."4. Ordinarily, an ordinary minister performs a Catholic baptism, such as a deacon, priest, or bishop, but in extreme cases anyone can. According to Catholic teaching, anyone can receive a baptism, unless they have been baptised before using the Trinitarian formula.…
