Describe the Data Mining Functions Data Mining Techniques?
Data mining refers to the broadly-defined set of techniques involving finding meaningful patterns - or information - in large amounts of raw data. At a very high level, data mining is performed in the following stages (note that terminology and steps taken in the data mining process varies by data mining practitioner): 1. Data collection: gathering the input data you intend to analyze 2. Data scrubbing: removing missing records, filling in missing values where appropriate 3. Pre-testing: determining which variables might be important for inclusion during the analysis stage 4. Analysis/Training: analyzing the input data to look for patterns 5. Model building: drawing conclusions from the analysis phase and determining a mathematical model to be applied to future sets of input data 6. Application: applying the model to new data sets to find meaningful patterns Data mining can be used to classify or cluster data into groups or to predict likely future outcomes based upon a set of input variables/data. Common data mining techniques and tools include, for example: a. decision tree learning b. Bayesian classification c. neural networks During the analysis phase (sometimes also called the training phase), it is customary to set aside some of the input data so that it can be used to cross-validate and test the model, respectively. This is an important step taken in order to to avoid "over-fitting" the model to the original data set used to train the model, which would make it less applicable to real-world applications.
Is pre test and post test qualitative data collection?
yes
How can you collect data to test your hypothesis?
Through observation, survey, or secondary data
What is the purpose of samples of impact test being notched?
In a charpy impact test, the purpose of the notch is to provide a point of fracture at the same point for each material, to make it a fair test.
What are 3 advantages of data validation?

What is the purpose of Matrikon?
The purpose of Matrikon is to simulate and test for an OPC compliance by providing simulated data to OPS clients. It works well with the Windows 2000 software.

What do you do to test a hypothesis?
IN more and more modern investigation the hypothesis is not tested. Rather undirected investigation takes plasce, a pattern is noticed and an explanation might be attempted but often it is not. A good example : Data Mining.
What is extreme test data?
Extreme test data is data that is on the boundary. eg if you were asked to enter an age between 1 - 100 extreme test data would be 0 and 101 It is on the boundary of normal test data (Normal test data is within the boundary) Hope i could help
Purpose of the test in education?
The purpose of the test in education serves a double purpose. The test is an assessment of what the student has learned. It is also a measure of the quality of the teaching.
What kind of test analyze data for experimental treatments?

What is the purpose of test exit criteria in the test plan?
To determine when a test has completed.
What is the purpose for iodine test?
The Iodine test is used to test for the presence of starch.
What is the purpose of performing the preliminary test for blood?
to test for aids
What is the purpose of the substantive test?
To test the validity of an account balance.
For what purpose is the sit and reach test used for?
The purpose of the sit and reach test is primarily to test one's flexibility. By seeing how far one can reach past their toes, they can test their flexibility.
