Histograms: Snapshots of Process Variation Histograms A histogram is a specialized type of bar chart. Individual data points are grouped together in classes, so that you can get an idea of how frequently data in each class occur in the data set. High bars indicate more points in a class, and low bars indicate less points. In the histogram show above, the peak is in the 40-49 class, where there are four points. The strength of a histogram is that it provides an easy-to-read picture of the location and variation in a data set. The first is that histograms can be manipulated to show different pictures. Histograms can also obscure the time differences among data sets. Histogram statistics: For histograms, the following statistics are calculated: Specification Limits and Batch Performance Where relevant, you should display specification limits on your histograms. When you overlay specification limits on a histogram, you can estimate how many items are being produced which do not meet specifications. Center of a Distribution
Hear the Voice of the Customer Using Customer Survey Software | Creative Research Systems Blog Any customer survey software can provide valuable insights, but some software and some insights can be more valuable than others. Any well-designed survey can provide some insights, but the more you can really get into the mind of the customer, the more you can learn. The greatest insights come from knowing what your customer is really thinking. The answers to multiple choice and rating questions can tell you some of what they are thinking, but the answers to comment type questions can tell you more. The way you collect comments can limit how useful those comments are.

The Survey System can play the comments back grouped by respondents’ demographic characteristics, helping you know what kinds of people gave the different answers.

Focus Groups Focus Groups Purpose This tutorial addresses strategies for using focus groups as a method of collecting information for program evaluation. Introduction Focus groups are a method of group interviewing in which the interaction between the moderator and the group, as well as the interaction between group members, serves to elicit information and insights in response to carefully designed questions. When to Use Focus Groups Focus groups, like any other program evaluation method, are more appropriate for some situations than others.

A Beginner's Guide to Mean, Median and Mode An average summarises a group of numbers. There are three main types of averages: mean, median and mode. Each of these will be looked at in turn. Mean This is the most commonly used average. Example - Here is a sample of numbers: The first thing to do is add the numbers up. All that is left to do is divide this number by the sample size. Potential Problems - Mean averages have two linked problems: If you have a large number of small values with a few very large values in your sample, mean averages get skewed: the mean is nearer to the bigger values even though the small values there are more smaller numbers. Example of the Effect of Outliers - In this case, the number 100 has been added to the sample above: The sum of these numbers is 123. Median This type of average is the middle number in a sample and requires the numbers to be in order. Example - Here is a sample of numbers to illustrate median: To use the median, these numbers must be placed in order, like this: Mode Real-world Examples
