Usually, after obtaining a statistically significant F test from the ANOVA, one wants to know which of the means contributed to the effect (i. One could of course perform a series of simple t-tests to compare all possible pairs of means. However, such a procedure would capitalize on chance. This means that the reported probability levels would actually overestimate the statistical significance of mean differences.
Without going into too much detail, suppose you took 20 samples of 10 random numbers each, and computed 20 means. Then, take the group (sample) with the highest mean and compare it with that of the lowest mean. The t-test for independent samples will test whether or not those two means are significantly different from each other, provided they were the only two samples taken. Post-hoc comparison techniques on the other hand specifically take into account the fact that more than two samples were taken.
Technically, it determines a linear combination of the dependent variables that best predicts the group membership. Another related type of analysis that cannot be directly performed with breakdowns is comparisons of frequencies of cases (n's) between groups. Specifically, often the n's in individual cells are not equal because the assignment of subjects to those groups typically results not from an experimenter's manipulation, but from subjects' pre-existing dispositions.
If, in spite of the random selection of the entire sample, the n's are unequal, then it may suggest that the independent variables are related. For example, crosstabulating levels of independent variables Age and Education most likely would not create groups of equal n, because education is distributed differently in different age groups. If you are interested in such comparisons, you can explore specific frequencies in the breakdowns tables, trying different orders of independent variables.
However, in order to subject such differences to statistical tests, you should use crosstabulations and frequency tables, Log-Linear Analysis, or Correspondence Analysis (for more advanced analyses on multi-way frequency tables). Graphs can often identify effects (both expected and unexpected) in the data more quickly and sometimes "better" than any other data analysis method.
Categorized graphs allow you to plot the means, distributions, correlations, etc. The graph below shows a categorized histogram which enables you to quickly evaluate and visualize the shape of the data for each group (group1-female, group2-female, etc.
The categorized scatterplot (in the graph below) shows the differences between patterns of correlations between dependent variables across the groups. Additionally, if the software has a brushing facility which supports animated brushing, you can select (i. Frequency or one-way tables represent the simplest method for analyzing categorical (nominal) data (refer to Elementary Concepts). They are often used as one of the exploratory procedures to review how different categories of values are distributed in the sample.
In practically every research project, a first "look" at the data usually includes frequency tables.I am very disappointed with them - we only want a fair deal. My credit back 2 years ago was not good, and I left some small refundable deposit.
Sounds like a ripoff to me. Helpful 2 people found this review helpful Tiana of Marina Del Rey, CA Verified Reviewer Original review: Dec.
I have called in many times and spent many countless hours on the phone with them and my issue is still unresolved. They continuously keep repeating the same thing over and over to me even if it does not make sense. I do not recommend anyone to sign up with them. I have never experienced such horrible service as this especially with a major corporation.

I was on chat with them for about 45 minutes. Finally told them I had to go and just cancel my service. They kept trying to get me to get a different package and that they had some good deals.
I told them no, just cancel. I finally had to sign off the chat, thinking that my service would be cancelled as requested. Well, as of Dec. Again they kept trying to get me to switch packages and said they had some great offers. After chatting about 20 minutes I was told that I had to be transferred to another department.
Another person started chatting and, once again, kept trying to get me to switch and telling me about the "great deals" available.
They kept me online for about another 20 minutes before I finally told them to click the box on their screen to cancel my service. After giving them the same information that I had given them in November, they finally cancelled the service after about another 10 minutes or so. Because of the runaround they gave me and jerking me around, I would never recommend DirecTV to anyone nor will I ever get their service again.
If they had just cancelled the service as requested I might have gotten their service again in the future. Stay away from DirecTV. It took me over 20 minutes on 3 occasions to get a customer representative. It wouldn't take as long to get a customer service rep If they didn't have to read a script. A simple 2 minute call takes 20 minutes.Use this tool to create annotations you can embed in your PDF.

We were a bit bummed that it snowed the second day, but that only last a little bit. Since moving to the UK the kids haven't seen snow, so it was fun to have a snowball fight.
Thanks for everything, the trip was grand. Renee, United States The Natural Wonders of Iceland, July 2016 Anita was great. She set up our itinerary and had things lined up and answered all my questions promptly and efficiently. Tour guide was awesome.
I cannot praise her highly enough. She was highly professional, and still warm, personable, friendly, incredibly knowledgeable and handled a diverse group beautifully.
The greenhouse was fascinating. And, I thought the addition of a few hours at a local farmer's home was the icing on the cake. We got to meet a farmer and his family and get a sense of what life is like for them. I was sorry to leave and want to come back. Alan, United Kingdom Majestic Highlights of Norway, July 2016 Despite the weather this was a thoroughly enjoyable holiday. Many thanks to Petra for her excellent organisation and responding quickly to our specific requirements.
Michael, United States South and West in Detail, July 2016 Difficult to pick out one thing, as everything was flawless.
The hotels were excellent, the car rental was very smooth. The trip planner was very well prepared and the confirmation tickets (which I actually didn't need most of the time as the hotels and drivers expected us) were excellent. Meals were uniformly good. Can't think of anything else to say. One of the best, most organized and carefree vacations we have taken.On average, a consumer will look at over 10 information sources before making a purchase tweet32.
