LEARNING RECORDS

Message 6553:

Vote Or Die!!!! Yes this is the solution to most of our problems. If people can get this misconception that one vote won't make a difference and will learn to voice their opinion through voting we will see a change. People fail to understand that if every person who thought this way would change their thinking then the votes would add up and we could win. The rich and powerful depend on our ignorance and lack of resource or knowledge to win their elections and pass laws that will keep the majority of society impoverished. If we as a society ever want to have the same opportunities then we need to even the playing field by voting and voicing our opinions. If people need proof that the majority of us are getting down played by the system, then all they need to do is look at different statistics. Numbers can say what words can't and that should be enough proof to motivate people to try and make a change. If that doesn't motivate them then maybe they should do it for the love of their children and relatives. If they fill that they don't care because the policies won't affect them then they should remember that it will eventually affect their kids or grandkids. So for the love of people PLEASE VOTE!!!!!!!!!

Nice plea for the understanding that every vote does count, even when it is honestly added up. It confirms our answerability, and when we raise our collective voices we are heard, even if it's only to fix the machines. At least they know we're there and that they must fix the machines to keep us at bay.

If your teacher wanted you to gather quantitative data on the use of the "N" word then she/he would want you to gather information that could be measured in numbers. Quantitative data is information such as that uses number or nominal scales to categorize people and to measure on numeric scales how they differ. For example you could measure how many people use the "N" word by taking a survey or you could take a survey to determine the variance of the use of the "N" word between ethnic groups. If the teacher wanted you to gather Qualitative data then they would want to go further than numbers can explain. Qualitative data uses dependent and independent variables to compare different aspects that might affect the outcome. For example, depending on a persons age the "N" word might have a different meaning. For an older person the word probably holds more of a demoralizing meaning then it would to a teenager. This would simply be due to the fact that when the older person was growing up the"N" word was used in a different context. Dependent and independent variables vary because you have control over one and not the other.

I think you covered a little too much in one gulp, Rene. Quantitative data may be collected in nominal, ordinal, interval, and ratio categories. Nominal means you can only name the categories, none being higher or lower than the other. Ordinal means that the categories can be ranked in order. Nominal means that we use equal intervals, like no. of years. Ratio, just adds a zero point to the interval data. All these are quantitative.

Your explanation of the different meaning of the N word to different cohorts is good.

Independent variables are the ones you manipulate, like gender, to see what will then happen to the dependent variable, which depends on the independent variable. Control has a slightly different meaning. It usually means that you hold one variable constant. For example, you study only males, as medicine did for a long, long time.

Message 5852:

WHEN THE DOCTOR SAYS, "BY CHANCE IT IS LIKELY TO REGRESS WHETHER THEY ARE TREATED OR NOT" IT MEANS THAT THERE IS A CHANCE THAT THE PATIENT'S MEDICAL CONDITION CAN GET WORSE EVEN IF THEY DECIDED TO GET TREATED. WHEN YOU TALK ABOUT REGRESSION IN TERMS OF THE MEAN, FIRST I TAKE THE MEANING OF THE MEAN. TO GET THE MEAN YOU MUST ADD ALL OUTCOMES AND THEN DIVIDE THE NUMBER OF OUTCOMES. REGRESSION MEANS THE DOWNWARD MOVEMENT SO I THINKING THAT IT MEANS THE THE MEAN WOULD GET SMALLER.

Reply:

This is incorrect, Rene. What the doctors mean by saying that the pain is likely to regress whether treated or not is that pain is variable, and at different times when you attempt to measure the pain, it is likely to be closer to the mean. Think of the bell curve. Most scores cluster around the average or mean, with fewer and fewer falling in the outlying areas. So if a 5 is the average on a 1 - 10 scale, most measurements will cluster around a 5, with fewer and fewer reaching 8, 9, 10. Regression toward the mean does not mean that the mean itself would get smaller. Interesting idea, but wrong.
