Introduction to Minitab for SixSigma

Three Statistical Analysis Function

Found in the menu bar at the top of Minitab. 1. Calc menu 2. Stat menu 3. Graph menu

What is one of the reasons for using Minitab?

a. It allows for creating data with utmost efficiency. b. It allows for analyzing data that otherwise would not be relevant. c. It allows for analyzing data and creates graphs or charts. d. It allows for analyzing data with utmost efficiency.

Statistics do not lie, but mathematics cannot evaluate what?

a. Non-numerical priorities b. Prepared priorities c. Numeric and non-numeric priorities d. Numerical priority

Central Limit Theorem

1. The theory that, as sample size increases, the distribution of sample means of size n, randomly selected, approaches a normal distribution. 2. CLT states that when dealing with continuous data, the larger the sample size, the closer the data will approximate the normal curve.

Choosing the Right Probability Distribution for Calc Menu

1. Use Binomial Distribution for binomial data, or data that deals with number of trials and event probability. In another word, the likelihood of one event or the other occurring for each trial. 2. Use Normal Distribution when you are dealing with data that is normal or approximates the normal curve.

In Minitab, when you are dealing with binomial data and a consistent event probability for every trial, which distribution should be used?

a. Non-random Distribution b. Poisson Distribution c. Multinomial Distribution d. Binomial Distribution

Random Data Function under the Calc Menu Option

This is one of three major capability of the Calc menu option found in the menu bar of Minitab. The random data tool lets you generate random data that conforms to a certain probability distribution. This tool is helpful when testing different capabilities in Minitab or practicing Six Sigma statistical analysis without your own data to start with. Also helpful if you want to compare your own data to various types of distributions.

Calc Menu Option inf Minitab

This is one of three statistical analysis functions found in the menu bar of Minitab. Calc menu has 3 major capabilities. 1. Generate random data 2. Calculate column or row statistics 3. Calculate probabilities given various distributions.

Probability Density Function (PDF)

The probability that a random variable, x, will occur in the data. E.g., In a given population of people, what is the probability that a random selected person will weigh 125 lbs.?

Cumulative Density Function (CDF)

The probability that a randomly selected data point will be less than or equal to a variable, x. E.g., In a given population of people, what is the probability that a randomly selected person will weigh less than or equal to 125 lbs.?

Column or Row Statistics Functions under the Calc Menu Option

Useful when you need to know a specific statistic about your data quickly. This function lets you calculate the sum, mean, standard deviation, min, max, range, median, sum of squares, or N total given data in a single column or row.

In Minitab, the worksheet window looks and behaves like what program?

a. A worksheet in Word b. A graph created with graphical analysis c. Begin with validated information d. A worksheet in Excel

Excel and Minitab accept what sort of entries that make them similar?

a. Alphabet and symbols b. Numerical and non-numerical c. Numerical and alphabet d. Numerical and alpha-numerical

In Minitab, what does CDF stand for in terms of functions?

a. Cumulative Division Function b. Cumulative Daily Function c. Creative Density Function d. Cumulative Density Function

In Minitab, what should be done before calculating probabilities?

a. Ensure you have the right distribution. b. Ensure you have the right data. c. Ensure you have the right information. d. Ensure you are using the correct function.

In Minitab, what is a major capability under the Calc menu option?

a. Generates graphs from data b. Calculates only columns c. Calculates only rows d. Generate random data

If you have data that follows a Binomial Distribution and you use Minitab to calculate answers based on the normal curve, what is an attribute of the result?

a. If you have data that follows a Binomial Distribution and you use Minitab to calculate answers based on the normal curve, your answers will be exact. b. If you have data that follows a Binomial Distribution and you use Minitab to calculate answers based on the normal curve, your answers will be incorrect. c. If you have data that follows a Binomial Distribution and you use Minitab to calculate answers based on the normal curve, your answers will be correct. d. If you have data that follows a Binomial Distribution and you use Minitab to calculate answers based on the normal curve, your answers will be formed into a graph.

In Minitab, the project window is where you can manage all of what?

a. Only charts and graphs b. Data, worksheets, charts, and graphs that still requires data input c. Data, worksheets, charts, and graphs you create with Minitab d. Data, worksheets, charts, and graphs you create with Excel

In Minitab, the calculate Column and Row Statistics functions allows for calculate of what?

a. Only mean and standard deviation b. Sum, mean, standard deviation, min, max, range, median, sum of squares, or N total given data in a single column or row c. Only N total given data in a single column or row. d. Only range and median

In Minitab, what does PDF stand for in terms of functions?

a. Probability Delay Function b. Portion Density Function c. Probability Division Function d. Probability Density Function

In Minitab, what does the random data tool generate?

a. Random data that conforms to a certain probability distribution b. Random data that does not conform into a certain probability distribution c. Validated data that conforms to a certain probability distribution d. Random data without distribution

In Minitab, how does the normal curve differ from binomial distribution?

a. The binomial distribution is a bell-shaped curve showing a particular distribution of probability over the values of a random variable. b. The binomial distribution deals with number of trials and event probability. c. The binomial distribution deals with the median and range. d. The binomial distribution deals with only sum of squares.
