Answer:
experimental
Explanation:
Experimental design: In research methods, the experimental design is referred to as a specific way of designing an experiment by a researcher to get valid as well as objective results. It refers to a collection of various research designs that is responsible for using controlled testing and the manipulation procedure to get knowledge of the causal processes. In most of the experimental design, one or more than one variables are being manipulated to know its effect on the dependent variable.
In the question above, the given statement signifies the use of the experimental design.
Answer:
Strong positive
Explanation:
In studies, we usually establish relationships between two or more variables using correlations. Correlations tell us how this variables are related.
- Two variables have a positive correlation when if one increases the other increases too.
- Two variables have a negative correlation when if one increases the other decreases and vice versa.
Also, a correlation can be weak, moderate or strong. Researchers agree that a correlation that is larger than 0.70 should be considered a strong correlation.
In this example Isabella reads about a study saying there's a correlation coefficient of +0.85 between hours spent studying and final exam grade. <u>The fact that the sign of this correlation is "+" tells us that it is positive</u> (the more hours spent studying, the better final exam grade). We can also see that <u>the coefficient is 0.85 which is greater than 0.70 and therefore we can consider this correlation as a strong one.</u>
Thus, Isabella would conclude that this is a strong positive relationship.
Answer: If they are not complementary, then the light passes through the object or gets reflected.
Explanation:
Mostly because of the inexperience of the engineers who had been entrusted with the tasks as most of them were professional lawyers. the length of the canal also cast more shadow of doubt on the undertaking besides the lack of sophisticated equipment for the engineering works.
I seen nothing because theres literally nothing to see
