Answer: having your control group chosen by random

Step-by-step explanation: so basically you do not plan who or what your control group and experimental group is, they are chosen at a random and lucky guess.

Answer:

Definition. A study design that randomly assigns participants into an experimental group or a control group. As the study is conducted, the only expected difference between the control and experimental groups in a randomized controlled trial (RCT) is the outcome variable being studied.

Step-by-step explanation:

Find the area of this kite
SVETLANKA909090 [29]

Answer:

26 units^2

Step-by-step explanation:

the area of a kite is (d1 * d2)/2

d1 = 2 + 2 = 4

d2 = 6 + 7 = 13

4 * 13 = 52

52 / 6 = 26

26 units^2 is your answer

Please, I really need math help.
Nostrana [21]

 

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(-3/2) = -1......( perpendicular to a line with a slope of -3/2)
a = 2/3        y=(2/3)x+b
the line that passes through (-2, -2) :- 2 = (2/3)(-2)+b
b = -2/3
<span> the equation is :  y  = (2/3)x-2/3</span></span>

<span><span>y =(2/3)(x-1)</span></span>

$307.1 x 0.85 = 261
$261 x 0.85 = 221.85

why is normal distribution important in statistics and in everyday life? give examples to underscore your points.
Ymorist [56]

Because it accurately depicts the distribution of values for many natural occurrences, it is the most significant probability distribution in statistics.

The most significant probability distribution in statistics for independent, random variables is the normal distribution, sometimes referred to as the Gaussian distribution. In statistical reports, its well-known bell-shaped curve is generally recognized.

The majority of the observations are centered around the middle peak of the normal distribution, which is a continuous probability distribution that is symmetrical around its mean. The probabilities for values that are farther from the mean taper off equally in both directions. Extreme values in the distribution's two tails are likewise rare. Not all symmetrical distributions are normal, even though the normal distribution is symmetrical. The Student's t, Cauchy, and logistic distributions, for instance, are all symmetric.

The normal distribution defines how a variable's values are distributed, just like any probability distribution does. Because it accurately depicts the distribution of values for many natural occurrences, it is the most significant probability distribution in statistics. Normal distributions are widely used to describe characteristics that are the sum of numerous distinct processes. For instance, the normal distribution is observed for heights, blood pressure, measurement error, and IQ scores.
