Direct information contains a bias in favor of that particular product or service.
Taking years as input variable and population of that city as output variable, let y represent the population after 1985 and y represent the population in and index of 1000. Linear regression is a modeling relationship that exists between the variable.
The equation, therefore, can be derived in Y=a+bX. In this case, Y is the independent variable that is drawn on the axis of the graph while X represents the variable plotted on the x-axis of the graph; finally, b is line slope.
Answer:
A control should have been included in the investigation
Explanation:
It is impossible for the student to interpret a correct conclusion about his experiment, without adding a control treatment where he can really compare the differences between the variables.
Control treatment is an element of research that receives all factors, except the variable being tested. The control serves to make comparisons with the other treatments, allowing to observe the exact difference between a system where the variable was tested and the system where it was not.
In the case of the question above, it would have been necessary for the student to have placed a cart on a ramp of normal height and without sandpaper. That way he could compare the speed between this cart and the carts on the other ramps, thus having a correct result.
B. are more advanced in their theory of the mind
Children who are bilingual by the age of 5 have a more advanced mind due to the fact that they could take in and learn that material at such a young age.
