Answer 3

let me jus paste a small part

Inductive reasoning is the opposite of deductive reasoning. Inductive reasoning makes broad generalizations from specific observations. Even if all of the premises are true in a statement, inductive reasoning allows for the conclusion to be false. Here’s an example: "Harold is a grandfather. Harold is bald. Therefore, all grandfathers are bald." The conclusion does not follow logically from the statements.

Answer 4

hop that helps

Answer 5

Mokeira is corret, an example of induction would be:
e.g 3. All students wear an ID. I saw a boy wear an ID therefore the boy is a student.

Answer 6

Sorry I was supposed to write deduction...

Answer 7

example number 3 is induction?

Answer 8

all are induction

Answer 9

They are all induction.
So there is a speculation made at the start of every example e.g I meet two students with ID. And a conclusion is made and applied to a larger sample. So think of a tree.
Induction is like starting at the bottom of the tree and spreading out onto many.

Answer 10

Deductive reasoning is a basic form of valid reasoning. Deductive reasoning, or deduction, starts out with a general statement, or hypothesis, and examines the possibilities to reach a specific, logical conclusion. The scientific method uses deduction to test hypotheses and theories.

In deductive reasoning, if something is true of a class of things in general, it is also true for all members of that class. For example, "All men are mortal. Harold is a man. Therefore, Harold is mortal." For deductive reasoning to be sound, the hypothesis must be correct. It is assumed that the premises, "All men are mortal" and "Harold is a man" are true. Therefore, the conclusion is logical and true.

It's possible to come to a logical conclusion even if the generalization is not true. If the generalization is wrong, the conclusion may be logical, but it may also be untrue. For example, the argument, "All bald men are grandfathers. Harold is bald. Therefore, Harold is a grandfather," is valid logically but it is untrue because the original statement is false.
