Question 1

Start will an alternative hypothesis-

Answer 1

Null hypothesis states that the results will not be significant. We have to accept that the null hypothesis is true until we can prove otherwise.

Question 2

P value/level

Answer 2

Level of probability/significant

Question 3

Type 1 error-

Answer 3

P value too Lenient/ too high.

Question 4

Type 2

Answer 4

P value too strict/ too low

Question 5

Interval-

Answer 5

Continuous data- equal level of measurements

Question 6

Ordinal-

Answer 6

Data can put into order

Question 7

Nominal-

Answer 7

Data in categories.

Question 8

Test statistics-

Answer 8

Observe value.

Question 9

Critical value-

Answer 9

Number you get after working out the calculations.

Question 10

Descriptive-

Answer 10

Describe our data through graphs.

Question 11

Inferential-

Answer 11

Describe our data through stats.

Question 12

P-levels-

Answer 12

P

Question 13

Significant?

Answer 13

If our test is significant, we can reject our null hypothesis and accept our alternative/experimental hypothesis.

If our test is not significant we can accept our null hypothesis and reject our alternative/experimental hypothesis

Question 14

Type 1 errors can be made when you reject a null hypothesis that is TRUE-

if the significant level is too high/lenient.

Answer 14

Type 2 errors occur when you accept the null hypothesis and that is false

If the significant level is too low/strict

Question 15

Justifying your choice-

Spearmans- hypothesis predicted is correlational- so test of correlation is needed- data is ordinal.

Answer 15

Chi-squared- data is put into categories- nominal data and IG design.

Mann Whitney- hypothesis predicts a difference between groups. IG- ordinal.

Wilcoxon- hypothesis predicts that they’ll be a difference between two conditions, RP

Question 16

Spearmans- Rho

Mann Whitney- U

Chi-squared- X2

Wilcoxon- T

Answer 16

After calculating the statistics that we end up with- is assigned a different name by the test we have used.
