Statistical studies in which researchers do not control variables of interest are uncontrolled experimental studies [C]. It refers to the variable in an experiment which could harm the connection between independent and dependent variables.
Further explanation :
An uncontrolled experimental study is a part of statistics. It means you conduct research that its object uninfluenced by anything or anyone. This distinguishes importantly from a controlled study in which a researcher defines and limits all parameters and variables concerned.
Regardless of the type of research conducted, there are three types of variables commonly used in an experiment, they are:
• Independent variable
The independent variable is the factor that you deliberately modify or regulate to see what effects it has. For example: in research to determine the impact of temperature on plantation pigments, the independent variable (cause) is temperature, while the quantity of pigment color is the dependent variable (the effect)
• Dependent variable
This refers to the variable being tested in research. It is ‘dependent’ on the independent variable. It is the one to be measured when you are taking data in research. For example: in research to find the best chicken that produces the largest eggs, here the dependent variable is the egg size. Because it depends on the breed of chicken (the independent variable).
• Constant variable
Constant variable or also known as the controlled variable is a variable that may vary, but the experimenter deliberately keeps constant so that the relationship between the independent and the dependent variable is more clearly isolated.

Venus is known for its hellishly hot surface temperatures. But it has other distinctions too, such as ______.
A. It's the brightest natural object in the sky
b. it's the planet furthest from earth
c. it has a strong magnetic field
d. it rotates in the opposite direction to most other planets
Venus is known for its hellishly hot surface temperatures. But it has other distinctions too, such as it rotates in the opposite direction to most other planets .
Answer: Option D
Explanation:
Venus is very hot because it gets surrounded by a dense atmosphere, about 100 times greater than Earth's atmosphere. When sunlight shines in this atmosphere, it causes more heat on the surface of Venus.
Heat accumulates and develops to very high temperatures. Venus revolves around its axis, unlike most planets. This means that on Venus, the sun appears to raise in west and descend in the east. On Earth, the sun usually rises in east and descends west.
The year of Venus - the time it takes to rotate around the sun - 225 earth days. Usually, this means that the days of Venus are so long than a year. However, due to the interesting reterograde rotation of Venus, the time period from one east to next is only 117 earth days.
Classical conditioning involves _____ while operant conditioning involves _____. behavior emitted by an organism; behavior elicited by a stimulus\
Classical conditioning involves behavior elicited by a stimulus because the classical conditioning occurs when the person produced an unconditioned response after being expose or associated with an unconditioned stimulus, by this, this is described as a behavior being produced because of a stimulus.
While operant conditioning involves behavior emitted by an organism because this process involves of a behavior being modified because of a punishment or either a reward in which the behavior is being emitted due to the reward or punishment.
Classical conditioning involves learning through association while operant conditioning involves learning through consequences.
Explanation:Classical conditioning involves learning through association, where a previously neutral stimulus comes to elicit a response when paired with a stimulus that naturally elicits that response. An example is Pavlov's dog experiment, where the dog learned to associate the sound of a bell with food, causing it to salivate in response to the bell alone. On the other hand, operant conditioning involves learning through consequences, where behaviors are strengthened or weakened based on the consequences they produce. An example is a rat learning to press a lever to receive a food reward.

Suppose that men leave their wives to marry other women more frequently than wives leave their husbands to marry other men. evolutionary psychologists would be most likely to explain this in terms of male-female differences in
Evolutionary psychologists would most likely explain this in terms of male-female reproductive capability disparities.
What is the reproductive capability?The ability to “create new creatures by either sexual or asexual ways from existing ones” is referred to as reproductive capability. Higher species reproduce sexually, and their reproductive organs, cells, and hormones all play a role in the process.
Fecundity refers to an organism's reproductive capability (the number of children it can produce). The greater an organism's fecundity, the less energy it is expected to invest in each child, both in terms of direct resources (such as fuel reserves deposited in an egg or seed) and parental care.
Reproduction is a biological process in which an organism reproduces biologically similar offspring. Reproduction allows and guarantees species continuation generation after generation.
Therefore, it is reproductive capacity.

After watching a documentary on ape intelligence, a student remarks that apes may be smart, but they lack the ability to use language. what would most likely be the professor's response?
Apes like Washoe, Koko, and Kanzi have demonstrated the ability to use gestures and symbolic systems, suggesting they possess some building blocks of language. They may have a capacity for protolanguage, a simpler form of language that could precede human language.
While it is true that apes do not use language to the same extent as humans, they do possess some building blocks of language. Research has shown that apes like Washoe, Koko, and Kanzi can use gestures and symbolic systems to communicate specific needs and comments.
These abilities suggest that apes may have the capacity for some form of protolanguage, a simpler form of language that could precede human language.
However, linguists are still debating whether apes truly understand the meaning of the words and gestures they use or if they are simply exhibiting conditioned responses.
Regardless, the linguistic accomplishments of these apes highlight their remarkable intelligence.

Quoting Steven Covey on time management would be using expert testimony because he is recognized as an authority on personal development and efficiency. Testimony, which includes expert testimony, is a form of knowledge gained through the words of others and is considered reliable if the source is trustworthy and an expert in the field.
Explanation:
According to your textbook, if you quoted Steven Covey, a professor at Brigham Young University and author of The Seven Habits of Highly Effective People, on the principles of effective time management, you would be using expert testimony. Expert testimony is when you gain beliefs based on the stated beliefs of others, particularly from someone recognized as an authority in their field. In this case, Covey is considered an authority on personal development and efficiency, thus his insights on time management would be regarded as expert testimony.
Testimony is a social means of gaining knowledge and involves relying on the communicated words of others, whether through speech or writing. This can include various sources such as news magazines, lectures, books, and casual conversations. When testimony comes from a trustworthy source, it is considered a reliable way to justify beliefs.

Can parents distinguish their own children by smell alone? to investigate, porter and moore (1981) gave new t-shirts to children of 9 mothers. each child wore his or her shirt to bed for three consecutive nights. during the day, from waking until bedtime, the shirts were kept in individually sealed plastic bags. no scented soaps or perfumes were used during the study. each mother was then given the shirt of her child and that of another, randomly chosen child and asked to identify her own child's shirt by smell. eight of nine mothers identified their children correctly. considering the null distribution table provided, what is the probability of obtaining 8 or more correct identifications?
Final answer:
The study by Porter and Moore (1981) demonstrated that 8 out of 9 mothers could correctly identify their own child's T-shirt by smell, suggesting that parents can indeed distinguish their own children by scent alone.
Explanation:
Can parents distinguish their own children by smell alone? In a study by Porter and Moore (1981), 9 mothers were given the task of identifying their own child's T-shirt, which the child had worn to bed for three consecutive nights, by smell alone. The T-shirts were kept in individually sealed plastic bags during the day, and no scented soaps or perfumes were used. Eight out of nine mothers were able to correctly identify their child's T-shirt.
To understand the likelihood of this happening by chance, we look at the null distribution table for the probability of obtaining 8 or more correct identifications by pure chance. Without the exact null distribution table provided in the question, a general approach suggests examining binomial probability.
Assuming each guess is independent and has a 50% chance of being correct (since each mother was choosing between her child's shirt and another), the probability of getting 8 or more correct out of 9 tries purely by chance is very low, and this result suggests that mothers can indeed distinguish their children by smell with significant accuracy.

shelley can paint a fence in 8 hours. Karen can do it in 4 hours. How long will it take them to do the job if they work together
The correct answer would be x=2.67 hours.
Explanation:
Shelly can paint a fence in 8 hours
Karen can paint a fence in 4 hours
Total time by Shelly and Karen to paint a fence = x
The time they will require to paint a fence if they work together is as follows:
1/8 + 1/4 = 1/x
(1*x)/8x + (1*2x)/(4*2x) = (1*8)/(x*8)
x/8x + 2x/8x = 8/8x
LCD 8x
x + 2x = 8
3x=8
x=2.67 hours.
So the total time taken by Shelly and Karen to paint a fence together would be 2.67 hours.

Shelley and Karen's combined rate of work is 3/8 of the fence per hour. By taking the reciprocal of this combined rate, we find that they can paint the fence together in 8/3 hours, or approximately 2 hours and 40 minutes.
When Shelley and Karen work together to paint a fence, we have to find their combined rate of work to determine how long it will take for them to complete the job. Shelley can paint the fence in 8 hours, which means her rate is 1/8 of the fence per hour. Karen can paint the same fence in 4 hours, which gives her a rate of 1/4 of the fence per hour.
To find the combined rate, we add the individual rates of Shelley and Karen:
Shelley's rate: 1/8 fence/hour
Karen's rate: 1/4 fence/hour
Combined rate: 1/8 + 1/4 = 1/8 + 2/8 = 3/8 fence/hour
Now, to find the total time it takes for them to paint the fence together, we take the reciprocal of the combined rate:
Total time = 1 / (3/8) = 8/3 hours
So, when working together, Shelley and Karen can paint the fence in 8/3 hours, which is approximately 2 hours and 40 minutes.
