Stats

Question 1

What does Statitical Analysis signifies

Answer 1

Statistical analysis is a scientific tool that helps collect and analyze large amounts of data to identify common patterns and trends to convert them into meaningful information. In simple words, statistical analysis is a data analysis tool that helps draw meaningful conclusions from raw and unstructured data.

Statistical analysis, or statistics, is the process of collecting and analyzing data to identify patterns and trends, remove bias and inform decision-making

Question 2

What are two main types of Statistical Analysis

Answer 2

Descriptive

Inferential

Question 3

What Does Descriptive Analysis Measure

Answer 3

1. Central Tendency ( Average, mean and mode)
2. Variability

Descriptive statistics describes data (for example, a chart or graph)

Question 4

What does Infernertial Analysis Evaluates?

Answer 4

1. Null hypothesis
   a. Evaluated how well the results from a sample can be inferred to the general population AKA Confidence interval Concepts
   b. Power Concept - the likely hood that the results were due to change

inferential statistics allows you to make predictions (“inferences”) from that data.

Question 5

What are the 4 Type of Analysis

Answer 5

Intention to treat (ITT)

Modified ITT

As treated

Per Protocol

Question 6

Name 4 Attribute to ITT

(Intention to Treat )

Answer 6

1 Most conservative Analysis

2. Determine treatment effect under normal conditions
3. Includes all randomized subjects ( even if they did not recieve one dose)
4. Prevent bias introduced by difference in study patient in each group that were randomized

Question 7

Attribute to Modifed Intention to treat

Answer 7

1. Include all randomized subject who recievd at least one dose
2. Subjects data grouped according towhat treatmetn subject was randomized

Question 8

As Treated

Answer 8

1. Include all. randomized subjects
2. Subject is data group to what treatment subjects actual recieved

Question 9

Per Protocol

Answer 9

a. Analysis includes only those subjects who followed the protocol exactly as written
b. Does not help distinguish between bias and treatment-related effects due to baseline differences
c. More generous estimate of the difference between treatment groups
d. May use in a noninferiority trial after analyzing data from ITT

Question 10

Describe Median, Mean, and Mode

Answer 10

Median - The middle number, but first you must arange in acening or descending order

Mean - AKA :rationof the sum of all observation or The Average

Add up all the number an divide by the amount of number

Mode - the most repeated number in a given set

Question 11

Types of Trials

What are the 3 types of Trial

Answer 11

1. Superiority – is the new intervention better or worse than control?
2. Equivalence – is the range for new product similar to the established equivalence range?
3. Noninferiority – is the new intervention no worse than control?

Answer 12

Nominal

Ordinal

Continous

Data Distribution
