If mean is 8 median is 6 and standard deviation is 2 what is skewness?
Karl Pearson simplified the topic of skewness and gave us some formulas to help. The first is the Pearson mode or first skewness coefficient. It is defined by the (mean-median)/standard deviation. So in this case the Pearson mode is: (8-6)/2 =1 There is also the Pearson Median. This is also called second skewness coefficient. It is defined as 3(mean-median)/standard deviation which in this case is 6/2 =3 hence the distribution is positive skewed
Find the coefficient of variation for first 'n' natural nombers?
I have found the coefficient of variation of the first natural numbers and also other functions.
What does a correlation coefficient represent?
The correlation coefficient for two variables is a measure of the degree to which the variables change together. The correlation coefficient ranges between -1 and +1. At +1, the two variables are in perfect agreement in the sense that any increase in one is matched by an increase in the other. An increase of twice as much in the first is accompanied by double the increase in the second. A correlation coefficient of -1 indicates that the two variables are in perfect opposition. The changes in the two variables are similar to when the correlation coefficient is +1, but this time an increase in one variable is accompanied by a decrease in the other. A correlation coefficient near 0 indicates that the two variables do not move in harmony. An increase in one is as likely to be accompanied by an increase in the other variable as a decrease. It is very very important to remember that a correlation coefficient does not indicate causality.
What is the first step you should take if you need to find the correlation coefficient for graph without using a computerized tool?
Stop taking PLATO
How can we avoid skewness in a data?
18-240 The best way to avoid skewness in data to show a log transform with intent. Log transform is the easy way to increase the the normality of distribution. Log transformation is most likely the first thing that remove skewness from the data.

What is a thermometer used for in a first aid kit?
To measure your temperature so if you have a cold, fever, etc you can manage the pearsons temp
When was sally pearsons first Olympics?
when did sally Pearson start Olympics
How does a box plot help when displaying a distribution of data?
A box plot summarises 5 key indicators of a distribution: the median, minimum, maximum and the lower and upper quartiles. The first of these is a measure of the central tendency whereas the others, in pairs, give measures of the spread as well as skewness.

How do you calculate the coefficient of friction?
It's hard to guess that in advance, though as a general rule you can guess that smooth surfaces have a lower coefficient of friction than rough surfaces, and lubrication usually reduces the friction. However, to get more precise information, this has to be measured. Of course, you can first search the Internet - somebody may already have measured it.

What is the first number called in an equation with 2 numbers and 1 operation?
coefficient
In a paragraph when you say First do you have to put a capital letter after?
No. It's not necessary. Example: First, compute for the greatest coefficient.
How can you find the coefficient of friction force only given mass and theta?
The coefficient of friction is the tangent of the angle theta where the angle is measured from horizontal when the mass first starts to slip
If all of the coefficient and constants in an equation are fractions what should your first step be?
To eradicate the denominators.
In which situation would you most likely factor out -1 from a trinomial?
If the coefficient of the highest power of a variable of interest is negative.
