How do you create an interaction term with a log transformed variable in SPSS?

How do you create an interaction term with a log transformed variable in SPSS? Topic: order a dissertation
July 20, 2019 / By Aiden
Question: I am analyzing my dissertation data and had to use a log10 transformation for one of my IVs because the distribution was skewed. I now need to create an interaction term using that transformed variable. In order to do that, does the transformed variable need to be centered by subtracting the mean from each value? I know that's what you normally have to do for IVs but I wasn't sure what to do with a log transformed IV. Thanks!

I don't think you will need to if the transformation actually adjusted for the skew. It would depend on the variable if you need too or not. I don't like manipulating my variables to much. I would have looked for new ways to transform the IV.

These mean pretty much the same thing in every science. The independent variable is what the experimenter is able to change/manipulate. If the experimenter intentionally changes it at the start of the experiment, that's your independent variable (IV). The dependent variable is what the experimenter is looking for. This is changed BY the IV and is measured at the end of an experiment. I'm a psychologist, not a biologist, so we don't usually use the term control variable. But what is universal is that anything that is NOT the IV or DV must be controlled as much as possible (and in this context "control" means kept the same). So a control variable is anything NOT the IV that you want to keep as similar as possible while your experiment is run. The reason you want to do this is that in a pure experiment where ONLY the IV changes, you can certainly know any changes in DV occurred due to the IV change (which you, clever experimenter, changed yourself). But if you had UNcontrolled variables, then how do you know changes in the DV weren't due to those variables, not your perfectly manipulated IV? Your time is wasted, or more research must be done, because that possibility exists.

Here it goes: Let's suppose you want to know how acid rain affects plant life. You hypothesize that the more acid rain, the more death you'll see in plants. So you plan an experiment to test your hypothesis. In this case, you can use three pots and plant seeds in each. In pot #1, water it with regular water (this is your control, what you will use to compare it to pots #2 and 3) three times daily. In pot #2, you will water it with slight acidic water, and in pot #3 with even more acidic water three times daily. Now that you've found a problem ,hypothesized, and planned the experiment, you now identify the dependent and independent variables. In this case, you'll be measuring the height of the plants (dependent variable). Dependent variables are the "things" you'll be measuring in the experiment, such as height and pulse rate. Your independed variables are the "thing(s)" you'll be changing in the experiment that will affect the dependent variables. In this experiment, it's the acidity of the water, since you're changing it from pot to pot. Essentially, the dependent variable (pulse rate) is affected by the independent variable (excercise). Date = Ind. Time = Ind. Age = Ind. Height = Dep. # of Children = Dep. Pulse rate = Dep. Gender = Ind. Hair Color = Dep. Birth Order = Ind.

This Site Might Help You. RE: What does independent variable, dependent variable, and control variable mean (in biology)? well i just need the definition of independent variable, dependent variable and control variable for biology. and experiment :D thanks!!!

Susie Originally Answered: If I have a string variable, then how to assign its specific element to a char variable in Visual C++?
Use the subscript operator "str[n]" where n is the index where you want to get the character. Strings are an array of characters and arrays are 0-indexed. The first element of the array "A" is the 0-th element, so we get it with data[0]. Now to set the character to "C", we do this:     a = data[2]; The variable a is now equal to the 3rd character "C". Hope this helped.

This is one of the enjoyable elements of C programming. A char array in C is terminated by means of a null character, escaped as ''. The char array should even be terminated by way of the length of the array however there is no such check in C. Hence causing lots of errors where the array is accessed out of bounds. So via initialising your constitution with zero you are placing a null ('') in aspect zero of list and a nil in age. The null in aspect zero means that your char array has a usable length of zero. Have enjoyable.
