Subject Title
Business Statistics Using Excel
Subject Description
The statistical methods of collection, analysis, presentation and interpretation of quantitative data used for making generalizations, projections and decisions under uncertain conditions are introduced. Emphasis will be on the use of both descriptive and inferential techniques within the workplace.
This course is equivalent to QNM222 in topic content. We teach the same theory and formulas as QNM222 but include substantial Excel analysis. The course is taught in a hybrid model of 3 hours of classroom instruction plus weekly online digital lectures. All classes are scheduled in a computer lab so we can use selfpaced practice questions that automatically adjust to student ability.
Credit Status
One credit.
Learning Outcomes
Upon successful completion of this subject the student will be able to:

Demonstrate the ability to present, describe, and summarize data by:
 identifying the different types of data and levels of measurement.
 differentiating between a population and a sample
 reorganizing raw data into arrays and grouped distributions
 presenting data by means of various tables and graphing methods using computer software/manual techniques
 calculating various measures of location and dispersion, including the mean, median, mode, percentiles, quartiles, standard deviation, and variance
 describing the shape of a distribution
 comparing and evaluating alternative methods of presenting data

Evaluate with the use of probability, the likelihood that a statistical inference is correct by:
 defining probability
 differentiating between subjective, relative frequency and classical approaches
 determining when events are mutually exclusive and/or statistically independent
 calculating probabilities using the rules of addition and multiplication

Determine the characteristics of selected probability distributions and identify where each distribution can be applied by:
 differentiating between discrete and continuous random variables

determining the probability of events and calculating the means (expected value) and standard deviations of:
 the probability distribution of a discrete random variable
 the binomial probability distribution

Recognize normal distribution problems and know how to solve such problems by:
 calculating the zvalue corresponding to any observation on a normal distribution
 determining the probability a random observation is in a given interval on a normal distribution

Use the central limit theorem to:
 calculate the mean and standard error of a random variable
 calculate probabilities for a given sample mean

Use sample data to make statements about the value of the population mean or proportion by:
 differentiating between a point estimator and an interval estimator
 calculating the point estimate for the population mean or proportion
 determining the confidence intervals for the population mean using sample mean and population standard deviation for large or small samples
 determining the confidence interval for population proportion for large or small samples
 computing the required sample size to estimate the population mean and population proportion for large or small samples

Construct and evaluate hypothesis test of a mean or proportion by:
 stating the null hypothesis and the alternative hypothesis
 indicating the appropriate test statistic
 establishing the critical values of the test statistic
 calculating the actual value of the test statistic and drawing appropriate conclusions

Perform simple regression and correlation analysis in business situations as indicated by:
 interpreting a scatter diagram
 determining and interpreting the correlation coefficient and the coefficient of determination
 differentiating between a dependent variable and an independent variable
 determining and interpreting the coefficients of the sample regression line
 using a regression equation to predict the value of the dependent variable for a selected value of the independent variable
 conduct a test of hypothesis for the coefficient of correlation and each coefficient of regression
 using spreadsheet software to perform the regression analysis
 interpret confidence intervals and prediction intervals for the dependent variable
Essential Employability Skills
Apply a systematic approach to solve problems.
Use a variety of thinking skills to anticipate and solve problems.
Take responsibility for one's own actions, decisions, and consequences.
Academic Integrity
Seneca upholds a learning community that values academic integrity, honesty, fairness, trust, respect, responsibility and courage. These values enhance Seneca's commitment to deliver highquality education and teaching excellence, while supporting a positive learning environment. Ensure that you are aware of Seneca's Academic Integrity Policy which can be found at: http://www.senecacollege.ca/about/policies/academicintegritypolicy.html Review section 2 of the policy for details regarding approaches to supporting integrity. Section 2.3 and Appendix B of the policy describe various sanctions that can be applied, if there is suspected academic misconduct (e.g., contract cheating, cheating, falsification, impersonation or plagiarism).
Please visit the Academic Integrity website http://open2.senecac.on.ca/sites/academicintegrity/forstudents to understand and learn more about how to prepare and submit work so that it supports academic integrity, and to avoid academic misconduct.
