FIRST STEP: Under the Transform menu, choose Visual Binning… This command assists you in creating a new variable that groups the data. You will then use the new variable to create a grouped frequency distribution.

• From the Variables list box, click on wt (weight) and then on the arrow to move it to the Variable to Band list box. Click Continue.

• Select wt in the left box. Near the top of this dialog box, enter a name for your new variable (such as wt_groups) in the “Binned Variable” box (cannot have any spaces in the name).

• Near the lower right, click Make Cutpoints…
• We are going to make Equal Width Intervals, which is the default selection in this dialog box. You have to fill in 2 of the 3 fields; for our purposes, fill in “Number of Cutpoints” and “Width”.

• As discussed above, generally 10 to 15 intervals works well. The Number of Cutpoints = [number of intervals – 1]. (Why? * ) Thus, if we want 10 intervals, we’ll enter 9 in the “Number of Cutpoints” box. • For the “Width” of each interval: (a) find the difference between the lowest and highest score in your data (you can see these values in the background dialog box behind the active dialog box); (b) divide the difference by the number of intervals (in this example, [122.7 – 65] / 10 = 5.77); and (c) round up to the whole number (6.0). Enter that number as the interval Width.

*

Because one cutpoint makes 2 categories. For example, if you have one apple and you "cut" it in half (one cutpoint), you have 2 apple halves. If you cut one of those halves (so now you have a total of two cuts to the apple), you'll have 3 pieces of apple. Make another cut (3 total cuts to the apple) and you'll have 4 pieces of apple, and so on.

So, you will always have one more category than you have cutpoints.

• Click in the First Cutpoint Location box, which should fill in automatically. In this example, the value 65.00 automatically appears. Click Apply to...

...Statistics:
• Science of gathering, analyzing, interpreting, and presenting data
• Measurement taken on a sample
• Type of distribution being used to analyze data
Descriptive statistics:
Using data gathered on a group to describe or reach conclusions about that same group only. Descriptive statistics are the tabular, graphical, and numerical methods used to summarize data.
Collect, organize, summarize, display, analyze
Eg: According to Consumer Reports, General Electric washing machine owners reported 9 problems per 100 machines during 2002. The statistic 9 describes the number of problems out of every 100 machines.
Inferential statistics:
Using sample data to reach conclusions about the population from which the sample was taken. Statistical inference is the process of using data obtained from a small group of elements (the sample) to make estimates and test hypotheses about the characteristics of a larger group of elements (the population).
Predict/forecast, make estimates about population behavior based on sample, , test hypothesis, make decisions
Eg 1: TV networks constantly monitor the popularity of their programs by hiring Nielsen and other organizations to sample the preferences of TV viewers.
Eg 2: The accounting department of a large firm will select a sample of the invoices to check for accuracy for all the invoices of the company.

LESSON PLAN
DISTRIBUTION BOXES
INTRODUCTION: (2 min)
1. Gain Attention: My first field operation here was an experience that I will never forget. We deployed to Thailand for Cobra Gold '03, I had been with artillery for four years, and I did not know what to expect. Hearing the stories about Thailand, getting a lot of liberty, and doing some shopping. Until an Army unit was attached with us, never working with a combined task force I did not know what to expect out of them. In the first week of installation we found out that these wire dogs were lazy and their tagging system was not user friendly. Working around the clock was not a fun part of the experience, trying to fix what these soldiers had easily messed up. Taking the time to do the job right the first time with tagging and inserting the correct lines in the J-boxes would had made the time in Thailand an enjoyable one.
2. Overview: The purpose of this period of instruction is to provide you information on the lengths of cables, how to clean cable, and how to identify and properly tag a distributionbox.

FrequencyDistributions
This assignment is based on FrequencyDistributions and will include the following information:
1. The ability to describe the information provided by the Standard Deviation.
2. The ability to use the Standard Deviation to calculate the percentage of occurrence of a variable either above or below a particular value.
3. The ability to describe a normal distribution as evidenced by a bell shaped curve as well as the ability to prepare a distribution chart from a set of data (module 3 Case).

... FrequencyDistribution
(A) Introduction
1. Ungrouped data versus grouped data
Ungrouped data (Raw data): It is a list of individual observed values of the random variable
Grouped data (a frequencydistribution): It is a table that displays the data in grouping along with the number of occurrences that fall into each group.
2. The components of a frequencydistribution
a. Class limits: They identify the inclusive values in a class of a frequencydistribution
The upper class limit (Lu) refers to the largest value that can go into any given class.
The lower class limit (LL) refers to the smallest value that can go into any given class.
b. Class boundaries: They are the specific points along a measurement scale that separate adjoining classes.
•A class boundary (Bu or BL) is the point halfway between the upper limit of one class and the lower limit of the next class.
•For discrete data, class boundaries are identical to class limits.
c. Class interval (i): It indicates the range of values included in each class.
•It is the difference between the upper and lower boundaries values of each class
•It is the difference between the upper (lower) limit of one class and upper (lower) limit of the next class.
•It is the difference between the class midpoint of two successive classes....

...FREQUENCYDISTRIBUTION
WHAT IT IS Frequencydistributions summarize and compress data by grouping it into classes and recording how many data points fall into each class. That is, they show how many observations on a given variable have a particular attribute. For example, a survey is taken of 50 people's favorite color. The frequencydistribution might indicate 15 people selected green, 12 blue, 6 red, 7 yellow, and 10 purple. Converting these raw numbers into percentages would then provide an even more useful description of the data. The frequencydistribution is the foundation of descriptive statistics. It is a prerequisite for both the various graphs used to display data and the basic statistics used to describe a data set -- mean, median, mode, variance, standard deviation, and so forth. Note that frequencydistributions are generally used to describe both nominal and interval data, though they can describe ordinal data.
WHEN TO USE IT A frequencydistribution should be constructed for virtually all data sets. They
are especially useful whenever a broad, easily understood description of data
concentration and spread is needed. Most data provided by third parties are
grouped into a frequencydistribution.
Preparation The steps in preparing frequency...

...I found the concept on frequencydistribution using Google and the search words “frequencydistribution” at http://www.mathsisfun.com/data/frequency-distribution.html
This website is geared towards younger people and therefore breaks down frequencydistribution into very basic terms: values and their frequency (how often each value occurs). The website uses the example of a child’s soccer team and how many goals they scored in recent games.
For the assignment this week, I have chosen to use the raw data of shoe sizes of my co-workers and how often these shoe sizes occur and show how to put them into a frequencydistribution table. Because there are only 4 females in my division, I have stuck with only the male shoe sizes of 20 co-workers.
Raw Data
10 12 9 10 11
8 10 11 10 9
9 8 11 10 10
12 10 9 10 11
Each raw data value is now placed into a class. Since my range of data is small, I’m going to use single data values.

Class Limits Tally Frequency

Total: 20
This can also be done in excel by following the instructions for a categorical frequency table for qualitative or discrete data on page 2-15 (49) of our textbook.
Taking it a step forward, the information can then be used in a pie chart to visually...

Instructor: Bell, Faith
A manager’s job is never ending, if you want to be successful in this business. Denny McKnight stated, “We think of best practices as doing all the right things with the right tools and getting the right results” (Harps, Best Practices in Todays Distribution). One of the marketing plans, distribution plays a key role to how products are exposed, stored and delivered, another key factor is the price of the products. Satisfying the customer making a product available either using direct or indirect means makes the difference when it comes to profit. Managing a restaurant, finding new ideas to expand this business as a whole, but more of a trademark, a name to be known by anyone and everyone. Distribution is very important, even for a small family own restaurant, choosing the best method can determine the success or failure of the business. Selling our own salsa homemade allows us to save or spending and gaining more in profits. Networking with companies and partnering with stores for shipping of products used to make the salsa since we started to grow our own vegetables to stay fresh. Buying another freezer storage to store our very own product right here at the restaurant. We choose not to buy or use a warehouse, only if we expanded and went stateside into selling the salsa, we decide to stay local. We contracted...
