Hypothesis Testing

Front 1

Research Hypothesis (H1)
-definition-

Back 1

Declarative statement that states how 2+ variables are believed to relate

Front 2

Null Hypothesis(H0)
-definition-

Back 2

States there is No real relationships or differences between the variables

Front 3

Nondirectional is --tailed

Back 3

2

Front 4

Two-tailed hypothesis
-definition-

Back 4

2 variables are expected to relate, but NO predicition on the direction is made

Front 5

Directional is --tailed

Back 5

1

Front 6

One-tailed hypothesis
-definition-

Back 6

2 variables relates and predicition made on the direction

Front 7

Steps in Hypothesis Testing

Back 7

1) State H1
2) State H0
3) Specify Signficance Level
4) Compute stats
5) Decide on H0

Front 8

Signficance level is also known as an...

Back 8

Alpha level

Front 9

Alpha Level
-definition-

Back 9

Indicates the risk taken in rejecting the H0

Front 10

Decision Rule
-definition-

Back 10

Specifies what values will prompt a rejection or keeping of the H0

Front 11

Statisticall Signficant
-definition-

Back 11

Mathematicla proability of the even occuring by chance is less than the rejection level set

Front 12

Type 1(I) Error
-definition-

Back 12

Rejected the hypothesis tested when it was true.

Front 13

Type 2(II)Error
-definition-

Back 13

Failed to reject the hypothesis tested when a given alternative hypothesis was true.
