Student Spending

Abstract We used a stratified random sample to examine the spending patterns of a traditional student population at one large residential university in a small Midwestern town. Juniors and seniors spent more than underclassmen on recreation, food, general merchandise, and miscellaneous items. Male students spent more on recreation (40 percent more) while females outspent males on books and school supplies. Off-campus residents spent about twice as much on recreation, as well as more on food and for general merchandise. Those paying all their college expenses spent more overall and on general merchandise, food, and utilities. Students paying none of their college expenses spent less overall and less on gasoline and total miscellaneous items. Students who worked spent more overall and…

Level of measurement

1. What demographic variables were measures at least at the interval level of measurement? a. The number of hours worked per week and the length of labor (hrs) 2. What statistics were used to describe the length of labor in this study? Were these appropriate? a. Length of labor for both the control and experimental groups were described with mean and standard deviations. Yes, these were appropriate measures of statistics. 3. What other statistics could have been used to describe the length of labor? Provide a rationale for your answer. a. In addition to mean and standard deviations, mode could have been used in this study to describe length of labor. It would have given an understanding as to how…

Using Statistics To Describe A Study Sample

Most studies describe the subjects that comprise the study sample. This description of the sample is called the sample characteristics which may be presented in a table or the narrative of the article. The sample characteristics are often presented for each of the groups in a study (i.e. experimental and control groups). Descriptive statistics are used to generate sample characteristics, and the type of statistic used depends on the level of measurement of the demographic variables included in a study (Burns & Grove, 2007). For example, measuring gender produces nominal level data that can be described using frequencies, percentages, and mode. Measuring educational level usually produces ordinal data that can be described using frequencies, percentages, mode, median, and range. Obtaining…

The ACL Benford command

A. 1. The ACL Benford command counts the times each digit or digit combination occurs in a data set and makes a comparison between actual count and expected count. The output of the command is showed in a graph and includes Z-statistic for each count to help evaluate the significance of deviation between actual and expected counts. 2. The use of Benford command provides auditors and other data analysts caution on that there are possible anomalies in large data sets which deserve further analysis. 3. The Benford command is activated by benford formula. Users can select Analyze from the menu bar and choose Perform Benford Analysis to display the Benford dialog box. B. 1. These Characteristics are following: comprised of…

Anxiety and Country

Answer: This study examined differences in anxiety level between an industrial country and a nonindustrial country. Anxiety is assessed three ways—cognitive, affective, and behavioral—with higher scores indicating higher levels of the anxiety dimensions. Directions: Using the SPSS data file answer the following questions. NOTE: Helpful hints are provided here for you to use while answering these questions. 1 What is the ONE independent variable in this study? What are the dependent variables? The independent variable is COUNTRY (Industrial and Non-Industrial). The dependent variables are Cognitive (COG), Affective (AFFECT) and Behavioral (BEHAVE). 2 Why is a one-way between-subject MANOVA appropriate to use for this research design? HINT: Consider the number of IVs and the number of DVs for your answer. Here…

When To Use Each Test

When to use each test? What is the sig value? Whether or not it is significant? Read output and tell you what that value means (significant or not) One sample: given population value and compare your sample to that population Know if its significant: analyze compare means, one sample t-test Independent sample t-test: lab one against lab five Two independent groups (compare their means) Significance use twotail Define the correct groups: Paired sample: only care about one lab and you look at before or after (temporal component) something has changed over time Compare what you were like at the beginning of the class and what they were like after the class ANOVA: test whether or not there is a significant…

Marriott Corporation” the Cost of Capital

What is the weighted average cost of capital for the Marriott Corporation and cost of capital for each of its divisions? – What risk-free rate and risk premium did you use to calculate the cost of equity? – How did you measure the cost of debt? – How did you measure the beta for each division? Solution What risk-free rate and risk premium did you use to calculate the cost of equity? – Risk-free rate proxy The risk-free rate is determined using the yields of U.S. Treasury securities, which are risk-free from default risk. U.S. Treasuries are subject to interest rate risk, therefore, the selected maturity should correspond to an investment horizon[1]. – Investment horizon According to the cost-of-capital calculation…

Quality Associates

Quality Associates, a consulting firm, advises its clients about sampling and statistical procedures that can be used to control their manufacturing processes. In particular application, a client gave Quality Associates a sample of 800 observations taken during a time in which that client’s process was operating satisfactorily. The sample standard deviation for these data was 0.21; hence with so much data, the population standard deviation was assumed to be 0.21. Quality Associates then suggested that random samples of size 30 be taken periodically to monitor the process on an ongoing basis. By analyzing news samples, the client could quickly learn whether the process was operation satisfactorily. When the process was not operation satisfactorily, corrective action could be taken to eliminate…

Standard Deviation

Standard deviation can be difficult to interpret as a single number on its own. Basically, a small standard deviation means that the values in a statistical data set are close to the mean of the data set, on average, and a large standard deviation means that the values in the data set are farther away from the mean, on average. The standard deviation measures how concentrated the data are around the mean; the more concentrated, the smaller the standard deviation. A small standard deviation can be a goal in certain situations where the results are restricted, for example, in product manufacturing and quality control. A particular type of car part that has to be 2 centimeters in diameter to fit…

Epidermic cell observation

The sample of epidermal cells were taken from two onions instead of one onion (layer 6-10 from the first onion, layer 1-4 from the second onion) due to the time limit of experiment which may cause an inconsistency in raw data because the two onions are slightly different in preserved temperature, shape, and growing environment. When cell samples were taken from the second onion, some of the cells are frozen due to the preservation which causes a distortion of the shape of the cells and may result in errors of counts. Because of the time limit of this experiment, there is a limitation in the size of samples. When counting the cells, there is no strict rule on regarding or…

Descriptive statistic

Table 1 shows the descriptive statistics about the 74 models of automobiles released in the year 1978, these include the automobiles’ price, mileage, repair record, headroom, trunk space, weight, length, turn circle, displacement and the gear ratio with its corresponding results. In terms of automobiles’ price, it ranges to \$3,291.00 up to \$15,906.00 for the period of the said year. Its average price is \$6,165.26 with a standard deviation of \$2,949.50. It can be seen that prices are not close by to one another. With regards to mileage, the majority of the automobiles runs 41 miles for every gallon of gasoline, while the least runs only for 12 miles. The mean of mileage has resulted to 21.30 mpg, with a…
