What is the definition of misleading data?
mis leading data is data you get that is not true. It can telll you u spent $800 on a coat but actual cost $3.
What is the formula for q correlation?
Once you have figured out all the quadrants and their respective values, use:
q=a+b-c-d/a+b+c+d
For example if:
a=6
b=3
c=4
d=2
q=6+3-4-2/6+3+4+2
=3/15
for example
u have
1,2,3,4,5,6,7,8,9 ,,,,,,, here n=9 ,,,, odd number
here median is 5
when n is even number for example :
10,20,30,40,50,60 ,,,,,,,,, here n=6
median will be : (30+40)/2 = 35
so median is the middle value
and n here is number of observations.
hope this helps :))
How many even four digit numbers can be made using 0235 and 6 where the first digit is not 0?
For the number to be even it must end with either 0, 2 or 6.
As there is a limitation of the number starting with 0, consider those ending with 0 separately from those ending with 2 or 6 and add together the results
Ending with 0:
1st digit has a choice of 4 possible digits; for each of these
2nd digit has a choice of one of the 3 remaining non-zero digits; for each of these
3rd digit has a choice of one of the 2 remaining non-zero digits; for each of these
4th must be 0 and only 1 choice
numbers = 4 x 3 x 2 x 1 = 24
Ending with 2 or 6:
The 4th digit has a choice of 2; for each of these
1st digit has a choice of 3; for each of these
2nd digit has a choice of 3; for each of these
3rd digit has a choice of 2
numbers = 2 x 3 x 3 x 2 = 36
Total ways = 24 + 36 = 60 possible numbers.
What is the percentage of people who eat organic foods?
The answer as to the percentage of people who eat organic foods depends upon the compilation of country-by-country figures for a worldwide determination. In the United States, statistics from a Gallup poll conducted Wednesday, July 7 to Saturday, July 10, 2014, indicate that 45 percent of Unitedstatesians buy organic food, in contrast to 15 and 38 percent that respectively refuse to make, or reveal indifference to, organic food purchases. The figures represent an increase since a Harris poll whose interviews in October 2007 found about 30 percent of Unitedstatesians buying organic foods.

There are 4 possible outcomes yielding an Ace on the third draw without replacement:
a) Ace and Ace (first two cards) then Ace (third card) = 4/52 x 3/51 x 2/50 (24/132600) or
b) Non-ace and Ace then Ace = 48/52 x 4/51 x 3/50 (576/132600) or
c) Ace and Non-ace then Ace = 4/52 x 48/51 x 3/50 (576/132600) or
d) Non-ace and Non-ace then Ace = 48/52 x 47/51 x 4/50 (9024/132600)
Then it's just a+b+c+d
(24+576+576+9024) / 132600
=10200/132600
=0.0769 (about 7.7%)
or more simply 4/52 if you're in a hurry because the oolongteasup
How do you add oil to the front end on a 1989 Toyota pickup 4X4?
there should be a drain fill plug on the front your diff. Since you have the IFS probably the easierst way to get oil into it would be to use along piece of fuel line from the top of your engine to the fill plug and just fill it from under the hood rather fan fighting with the bottle underneith the truck.
Is a median number higher than a mean number?
Imagine that you have a list of 15 numbers for example. The mean is the average of those number. In other words, take the sum of all the numbers and divide by how many numbers there are (15 in this case). The median is the "middle number," and is found by arranging all the numbers in order of size and then picking the middle number. If you have 15 numbers, the 8th number is the middle one (there would then be seven smaller numbers and seven larger). If instead you have an even number of numbers, then you don't have a single middle number (you have two), and so you would take the average of the two middle ones (for example, if you have 16 numbers, you take the average value of the 8th and 9th numbers as the median). Whether the median or the mean is larger depends entirely on the specific list of number that you are analyzing.

If the first three angles of a square are right how is the fourth wrong?
it is not because then it wouldn't be a square.A square equals 4 90 degree angles and 4 equal sides.
How do you find the median if you have 3 numbers?
Add the 3 numbers together, and then divide the total by 3. This will give you the median number.
What is the range of the numbers -5 4 -7 5 13?
Range = 20.
The range is the difference between the largest value and smallest value in a population, and it roughly shows dispersion. For this case, it is 13 - (-7) = 20. For small population sizes, the range is not a good statistic.
Define equipment error and explain how to reduce it?
the equipment error is the percentage of uncertainty on the equipment, so for example, a measuring cylinder has the percentage error of around 0.5cm3. The only way I know off to reduce error percentage is to well increase sample size/ volume A etc. as the calculation is something like (equipment error / quantity measured x 100) this would mean that having a higher quantity to measure will therefore decrease percentage error. hope it helps.
