The further I get away from 0 for the skewedness the further I deviate from normal distribution. Non Skewedness is close to zero or away from 0. Statistics of zero indicates no skewedness at all.Mean is the most commonly used measure of central tendency and not very often will you use median. This is also because it is […]
A Confidence interval is a range of values that likely would contain an unknown population parameter. Confidence level refers to the percentage of probability, or certainty, that the confidence interval would contain the true population parameter when you draw a random sample many times. Confidence intervals are described broadly as tools for extracting necessary information […]
Describe how you think the research in the article is useful (e.g., what population is it helping? What problem is it solving?). Using Y=f(X) +E notation, identify the independent and dependent variables. How might the research models presented be wrong? What types of error might be present in the reported research? Women undergo […]
Many of our today’s knowledge of facts and findings are being achieved via experimentations and the use of quantitative analysis. Some of the concluded data by other researchers may be called unaccepted value of error. However, some errors occur in different stages of conducting research. For us to understand how errors € can be essential […]
For the Metric Variable of number of adults in household (ADULTCT), the descriptive statistics is below: The metric variable of number of adults in household show N=51451 with missing value of 136. The values for the mean, median and mode for this statistics are 3.64, 3.00, and 2. The std. error of mean is minute […]
Many of our today’s knowledge of facts and findings are being achieved via the burden of experimentations and making quantities or measurements. Some of the measurements done by other researchers may be called unaccepted value of error or may have missing details. However, I believed errors occur in many aspects of conducting research. For example, […]
As a lay audience, it is possible to understand what it meant to be positively correlated or negatively correlated. Pearson correlation coefficient has a standard index with a range value from -1.0 to +1.0, and with 0 specifying no relationship (Laureate Education, 2016b). The closer we move to the value of 1 the stronger the […]
As its name implies, confidence intervals provide a range of values, along with a level of confidence, to serve as an estimate of some unknown population value. Since it is rare to have access to the entire population, you must frequently rely on the confidence interval of the sample to make some inference about the […]
Our daily lives revolve around things that we cannot control. Before we step out the front door we ask, will it rain today? What is the chance of getting stuck in traffic? Or better yet, will my class be cancelled? Even though Dietz & Kalof (2009) suggest how life is uncontrollable, however; people try to […]
Project Ready Smile (PRS) provides services to children in selected early childhood settings in the six targeted counties in Missouri. ECC or early childhood carriers sites agree to support the project while providing access to children. Children were found with abscesses and tooth decay that had already spread through their mouth. PRS is an initiative […]
