Flow Chart is a generic term, and DFD is a specific one. Data Flow Diagram (DFD) is a data flow chart to illustrate the data flow/store/change in a component/system/product from the input to the output.

y - x = 5 so:

x = 1, y = 6 and all increments (and decrements) of 1 in each term, so there are an infinite number of solutions.

These are your 5 numbers:

X X X X X

the median (the middle number of a row) is 11, that means:

X X 11 X X

the mode (the most frequent number in a row) is 12, that means:

X X 11 12 12

the mean (the average) is 10, that means:

(X+X+11+12+12)/5=10

or: X+X+11+12+12=50

or: X+X=50-12-12-11

or: X+X=15

so the remaining numbers must be 15 combined, and lower then 11, that means they can be:

5 and 10

6 and 9

7 and 8

so you have 3 possible solutions:

5 10 11 12 12

6 9 11 12 12

7 8 11 12 12

Nothing, since there is no such word.

The answer is 10C7 = 10*9*8/(3*2*1) = 120

The answer is 10C7 = 10*9*8/(3*2*1) = 120

The answer is 10C7 = 10*9*8/(3*2*1) = 120

The answer is 10C7 = 10*9*8/(3*2*1) = 120

yes

It means that as one thing goes up, the other thing also goes up.

No. If the variable is continuous, for example, height or mass of something, or time interval, then the set of possible outcomes is infinite.

The Y-axis is also known as the Ordinate, while the X-axis is known as the Abscissa.

A compass is a geometric tool used to draw circles.

No, 2^3 = 8, 3^3 = 27, it is in between 2 and 3

4 aces

Any number 499 or less rounds to zero.

Any number 500 or greater rounds to 1000.

Ah, where are the good old days, when a score of 72 was always better than a score of 62,

and that was all you needed to know, and it didn't matter how well or poorly anybody else

in the class was doing ?

Sam Levinson used to tell about the time his son brought home a report card, and on the

report card the teacher had written "For him, he is doing good", and Sam used to say,

"Now all I need to know is: Who is 'him' ?"

There are 8*7/(2*1) = 28 combinations.

Biostatistics has a wide range of applications, primarily in public health, medicine, and biological research. It is essential for designing clinical trials, analyzing health data, and interpreting results to make informed decisions about treatments and interventions. Additionally, biostatistics plays a crucial role in epidemiology by helping identify risk factors for diseases and assessing the effectiveness of public health policies. Its methodologies are also applied in genomics, environmental studies, and healthcare quality improvement.

I think it means before assured of, or something along those lines.

Find the inter quartile range, which is IQR = Q3 - Q1, where Q3 is the third quartile and Q1 is the first quartile. Then find these two numbers:

a) Q1 - 1.5*IQR

b) Q3 + 1.5*IQR

Any observation that is below a) or above b) can be considered an outlier.

Chadwick, quartiles are considered robust, meaning that they are not highly effected by outliers. This is because it takes location into account, not the values. Let's look at your data set (sorted).

2 3 6 9 13 18 21 106

position of Q1 = (8+1)/4 = 2.25

Q1 = 0.75(3)+0.25(6) = 3.75

position of Q2 = (8+1)/2 = 4.5

Q2 = (9+13)/2 = 11

position of Q3 = 3(8+1)/4 = 6.75

Q3 = 0.25(18)+0.75(21) = 20.25

Notice that none of these actually use the value 106. Let's continue.

So IQR = Q3-Q1 = 20.25-3.75 = 16.5

Q1-1.5*IQR = 3.75-1.5*16.5 = -21

Q3+1.5*IQR = 20.25+1.5*16.5 = 45

No numbers are below -21, but 106 is above 45, so it can be considered an outlier.

The larger your sample size, the less variance there will be.

For instance, your information is going to be much more substantial if you took 1000 samples over 10 samples.
