Download file to see previous pages n various states of the US economy, it is important to find out how far the given observations are scattered around the mean observation for which the standard deviation is used as a reliable measure. For the same reason, this paper has also taken the support of a histogram. The purpose of a histogram is to find out the frequency density, i.e., how the observations are clustered within the different classes.
The data for the number of students enrolled in US public elementary schools is obtained from the 2004 report published by the US National Center for Education. This data has been used to find out the spread of elementary education among various states in the US economy. But, before progressing it is important to define some useful statistics that will help to draw empirical conclusions.
The degree of scatteredness is measured be the standard deviation; but before defining it, it is necessary to calculate the mean of the observations, because, the scatteredness of observations actually suggests how far they are dispersed about their mean value. Now, mean is defined as,
Besides, the coefficient of variation for the concerned data is also being calculated since it will help in finding out the percentage of variations present in the data being collected. Coefficient of variation is defined as,
The standard deviation statistic so obtained implies that the observations are rather too highly scattered about their mean value (670.2). This fact is prominent from the value of the coefficient of variation which indicates that the observations are scattered by a degree of 120% around their mean value.
The histogram derived from the data show that most of the observations are scattered towards the leftmost position in the graph, thus yielding a positively skewed curve. From the curve, however, one obvious point is that very few states have a high number of students enrolled in public elementary schools.

...and intention to patronize innovation in the product/process/management structure were incorporated (consensus validity), so that the respondent's overall score on the positive or negative attitude toward innovation could be obtained. Convergence reliability and divergence reliability can thus be established. In the study, a five-point scale was also used and it was felt that the five scale categories would absorb the variability in the responses of the respondents and at the same time produce a reasonably high reliability score. 3.4 Data Analysis All data will be analyzed and tabulated for both positive and negative adjustment, the frequency of responses will be calculated and descriptive statistics...

...thus effectively minimizes the objectivity of the data collected. These methods can be used as a means of comparing two groups in order to establish an underlying similarity or difference on a specific numerical variable or variables. These methods are especially useful in making inferences and generalizing the data obtained (Holden & Lynch, 2004). In collecting quantitative data, I would focus on more on concrete numbers rather than esoteric descriptions. The data collection would include the compilation of concrete numerical data such as financial statistics, employment statistics including pay rate, staffing levels and employee competencies. This data can be obtained through...

Thorough analysis of all data will be conducted. First, a descriptive analysis of distributions and relationships (n=77) was completed. Next, statistical testing and estimation was used to assess the current sample and population benchmarks in terms of cardholder demographics, to test changes in cardholder income from the previous year, and to examine the effects of demographics on the amount charged. Finally, regression modeling was used to create a model for predicting amount charged with given demographics information. Specifically, the following...

...Descriptive statistics Descriptive statistics Introduction Descriptive statistics entails a quantitative of data (Dodge, 2003). Its aim is to summarize a sample. The various measures used to describe a set of data, measures of central tendency, measures of dispersion and measures of distribution. Central tendency measurement involves mean, mode and median. Measures of dispersion include variance or standard deviation, minimum and maximum variables values, kurtosis and skewness (Trochim, 2006). Descriptive statistics produce sample summaries about observations. There are two types of summaries namely: quantitative and visual. Quantitative or summary statistics give only numbers while visual employs the use of charts or graphs... . The made...
