Bus 308 Statistics for Managers Complete Week 1 to 5

c. Perform a one-factor analysis of variance for the data. Write the table below and interpret the result.

4. For the questions 1-3 we found out a couple different cost functions that could be useful for Delta when predicting salaries for 2003 and 2004. The multiple regressions may be most reliable considering it uses multiple variables, but the single R square is better than multiple regressions.

a. For each year, create tables of counts of gender and of nationality. Then create column charts of

5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?

2. Compute the means for the following set of scores saved as Ch. 2 Data Set 3 using IBM® SPSS® software. Print out a copy of the output. (Please refer to attachment)

1. By hand (without using SPSS), compute the mean, median, and mode for the following set of 40 reading scores:

The results are as follows: the mean age of the sexual minority youth was 16.24 years old, female sexual minority youth were

My data collection consisted of three males, two females and ages from 19-60. The race categories

1. Using the data in the file named Ch. 11 Data Set 2, test the research hypothesis at the .05 level of significance that boys raise their hands in class more often than girls. Do this practice problem by hand using a calculator. What is your conclusion regarding the research hypothesis? Remember to first decide whether this is a one- or two-tailed test.

The summary includes variance, mean, median, mode and standard deviation. As shown in the histogram majority of people in the data pool have a height of 62-68 inches. This is a symmetrical distribution seeing how close the mean and median are to each other.

Observe skull sample and record the overall skull size, shape of forehead, supraorbital ridge, mastoid process, orbital shape, nuchal area and occipital protuberance and chin shape. Compare your observations with the information in lab book’s (table 8.1) characteristics to determine sex of the skull.

In analyzing the data they took the collected information from NLSY and divided the number of men supervised by the number of individuals working that were also supervised. This provided a continuous measure of sex composition (217) for the dependent variable. The main independent variable is set to a number of questions asked where individual answers are coded “1”. The researches continue on with the tabling of codes in order to come to their results either confirming or disproving their

To begin the statistical analysis of the data provided, we need to present the statistical description of it, take a general look at the means and medians for each sector and test the normal distribution of the data to see if we can undertake any further test.

Statistic preferred descriptive statistics. It involves the description of the major features of the data collected from a business. It tends to carry out a collective summary of the set of data extracted from the business characteristics. This summary is either visual or quantitative and simple in nature and looks at the sample observation and conclusions. The summaries conducted can either construct the baseline or foundation of the original data description as an active section of a complex and extensive analysis of statistics or form the essential framework of a given investigation. It is important to conduct a business statistical analysis so as to determine whether financial projections are geared towards profit making. The analysis is important for purposes carrying out the business plan update, which may be undertaken in different levels.
