Extract of sample "Choosing and Using Statistics"

This is an indicator that the points have a linear trend. The slope of the graph, 0.39, means that for every unit increase in performance in calculus, a student will attain a corresponding improvement of 0.39 in statistics. The y-intercept means that the minimum statistics marks that an acalculous student can score are 47.317.
Multiple R, defined as the coefficient of correlation is an indicator of the strength of the relationship between marks of the two subjects while R squared measures the proportion of the data that is explained by the model (Dytham, n.p.).
The distribution is skewed. This is because of the results obtained from descriptive statistics. The value corresponding to skewness is 0.131, as obtained from excel. This means that the values are slightly skewed to the right (Dytham, n.p.). Read More

... main effects are possible. A univariate analysis of variance (factorial ANOVA) was conducted on SPSS 18.0 to determine the significance of these three possible effects. The first thing to check when conducting a factorial ANOVA is Levene’s Test of the equal variance assumption. This test had a p=0.624, indicating that the equal variance assumption has not been violated. Since we can assume equal variance, we can use the given F and p statistics given in the between subjects table. The 4x2 ANOVA failed to demonstrate an interaction effect at the 0.05 error level between class and gender (F(3,32)=0.901, p=0.451), but did demonstrate a significant main effect for class (F(3,32)=18.342, p<0.001). Class had a partial eta-squared (effect size... Due Statistics Report II This study...

...?Because there are 50 numbers, we can divide these numbers into groups of 10 (5 groups). Next we subtract the lowest number from the highest number (76 — 16 = 60). After this, we will divide the difference by the number of groups that we came up with (60 / 5 = 12). Once we get the class width (12), we add it to the lowest number in order to get the lowest class limit (16 + 12 = 28). If we keep on repeating this step, we can determine all the appropriate class limits (28 + 12 = 40, 40 + 12 = 52, 52 + 12 = 64, and 64 + 12 = 76). Because these are the maximum limits, we have to subtract 1 from each class limit (16 + 12 — 1 = 27, 28 + 12 — 1 = 39, 40 + 12 — 1 = 51, 52 + 12 — 1 = 63). Now that we have worked this out, we can create... there are 50 ...

Presentation of statistics using a frequency

...of the example taken The example considered for this report is from the latest news release by Bureau of Labor Statistics, U.S. Department of Labor. The date of the news release was 2nd September, 2011. This news release basically depicts the employment situation in U.S. as of August, 2011. The example is a 38 page report with two types of data – household survey data and establishment survey data (depending upon the source of data). 2. Frequency distribution reporting Reporting by means of frequency distribution can be noted at a number of places in this example. It would be prudent to depict the same by means of Table 2.1 as shown below: Table 2.1: Use of frequency distribution in reporting data #...

Gas Prices: Data Analysis Using Descriptive Statistics

...?Gas Prices: Data Analysis Using Descriptive Statistics The price levels of gasoline and other sources of energy vary over time; however, there is a distinct variation in the prices of gasoline according to geographical regions, a fact that can be explained by diverse factors. The United States Department of Energy classifies different regions in the country according to their geographical placement, and this research study will try to compare the differences in gasoline process according to these regions. This study will be done through an application of descriptive statistics to price data for the different regions. This is done by correlating the price data, refinery locations, and the...

Analyzing the Data Set using Inferential Statistics

...There are usually five steps in using inferential statistics to test our claims about a particular scenario. These steps are as follows mentof the hypothesis. This is where we identify our null and alternative hypothesis. 2. Identify the critical value. This is identified by looking up the values in the z-distribution or t-distribution tables taking into consideration the required confidence interval. 3. Compute test value. The test value is computed using the appropriate formula. For the sample proportions (#1-4) and sample means and sample standard deviation(#5-6), I used the means from the table that was uploaded. Since questions 1 to 4 involve population...

..., particularly in the U.S. This research paper therefore aims at establishing the relationships between the changes in the GDP and house sales. In determining such relationships, this research paper will focus on literature material and the statistical inferences. Resources The link between GDP and the change in the sales of the housing and real estate units is evidenced by the data on the performance if these two variable over time. The data from the department of labor and economics show that these two variables have a strong positive relationship. This is evidenced by the great global economic and financial crisis of 2009 that negatively affected the housing and real estate sector through the housing bubbles. These...
