What is an example of a descriptive variable?
The colour of your hair, the district that you live in, your gender.
What type of correlation on a graph would there be for the color of a persons hair and their weight?
There would be no definite correlation. It would just be a random correlation that would be all over the graph because there is no trend in hair color and weight. Your weight doesn't determine your hair color.
What hair color has the most hair on average?
Blondes have the most with about 120,000 strands. Redheads have the least with 80,000. People with black or brown hair are somewhere in between the two. It's to do with the gene pool and nothing more! Has nothing to do with hair color.
What is the meaning of confounding in statistics?
In statistics. a confounding variable is one that is not under examination but which is correlated with the independent and dependent variable. Any association (correlation) between these two variables is hidden (confounded) by their correlation with the extraneous variable. A simple example: The proportion of black-and-white TV sets in the UK and the greyness of my hair are negatively correlated. But that is not because the TV sets are becoming colour sets and so my hair is loosing colour, nor the other way around. It is simply that both are correlated with the passage of time. Time is the confounding variable in this example.
What is a categorical variable in statistics?
WHAT THE HELL IS A CATEGORICAL VARIABLE! Actually hell may be an observation in a categorical variable what we might call "place of final rest". The term, categorical variable, can best be difined by examining it parts. The categorical part: a grouping of things with like characteristics, i.e., the going to hell group and the going to heaven group. Or how you group the women in a bar; the women with blonde hair, the women with red hair and the firey redheads. But notice there are different colors of hair; that is, hair color varies -- did I say varies? Yes I did. So when something varies or changes what do we have? A variable!! We can thing of hair color as a categorical variable. But notice also that we can think of sex as a categorical variable. But there can be only categories in the variable sex, male or female; unless your talking about the act of sex in which case, that is for me, there is only one category, infrequent. You might say that gender or sex can vary in only two ways, either you're male or you're female; there are no other choices. This means that the categorical variable has two degrees of freedom. How many degrees of freedom are in the categorical variable, sexual preference? So what do we have after all of this horseshit: things change; that is they vary. The number of blondes in a bar changes from night to night. Go to the bar and take a tablet with you. OK, you can scribble on a napkin if you want to...just don't get it soaked in beer. Write this prase at the top of the napkin: Number of blondes in the bar tonight." Beside that write the day, Monday, Tuesday, ect. Now sit and sip you draft and count the number of blondes on a Monday night and write that number down. 36 blondes on Monday night. Do the same for the other nights in the week. Here's the way your table might look: Day of Week Number of Blondes Mon 22 Tue 54 Wed 120 Thu 12 Fri 18 Sat 77 Sun 0 What can we say about the table. Well, we can say that we have counted the numberof blondes in the bar by day of the week. This is called tabulation or tallying. What are the categorical variales in the table? Notice anything unusual about Wednesday night?
Would the hair colour of students in a class be qualititive discrete or continuous?

What is a dependent variable for hair?

Is hair color continuous or discontinuous variation?
Hair colour is continuous because there is a continual range of values when it comes to hair colour
What are 3 examples of discrete variation in humans?
From a purist point of view, there is probably only a few true examples of discrete variation in humans. However, we have the common sense practical real world ways to describe some things as discrete. A coma scale used, Glasgow, is discrete. Also, vision is expressed as discrete values. See attached related links. In addition, number of seizures is discrete along with pulse (heart) rate.
Is natural hair colour continuous or discontinuous?
Natural hair color is a discontinuous trait, as it is determined by a small number of distinct genes that control the production of melanin in hair follicles, resulting in a limited number of color options such as black, brown, blonde, red, etc.

Is A variable that changes outside the control of the participants an independent variable?
Variables that may affect the results of an experiment are described by the umbrella term "extraneous variable". extraneous variables that actually affect the result without experimenter knowledge is called a confounding variables eg. if the experimenter is testing verbal recall performance, hair color is not going to effect the results. hair color is an extraneous variable, but not compound. but whether or not a subject had a good nights sleep can have a huge effect on the ability to remember words. therefore sleep is a compound variable.
Which is an example of continuous variation?
hair colour
