#2 Classification and tabulation of dataKawita Bhatt
The placement of data in different homogenous groups formed on the basis of some characteristics or criteria is called classification. The Table is a systematic arrangement of data in rows and/or column. Here, few basic concepts of classification and tabulation such as class interval, variable, frequency, frequency distribution and cumulative frequency distribution have been explained in a nutshell. This presentation also deals with the basic guidelines for preparing a table. Any suggestion and query are welcomed please drop them in the comments.
Statistical techniques for measuring the closeness of the relationship between variables.It measures the degree to which changes in one variable are associated with changes in another.It can only indicate the degree of association or covariance between variables. Covariance is a measure of the extent to which two variables are related.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

How to Build a Module in Odoo 17 Using the Scaffold MethodCeline George
Odoo provides an option for creating a module by using a single line command. By using this command the user can make a whole structure of a module. It is very easy for a beginner to make a module. There is no need to make each file manually. This slide will show how to create a module using the scaffold method.
This presentation was provided by Steph Pollock of The American Psychological Association’s Journals Program, and Damita Snow, of The American Society of Civil Engineers (ASCE), for the initial session of NISO's 2024 Training Series "DEIA in the Scholarly Landscape."

3. CONCEPTUAL QUESTIONS: -
1. What is relationship between height and
weight?
2. What is relation between age of husband and
wife?
3. What is the relationship between price and
demand?
5. Meaning of Correlation
Correlation is a statistical tools which shows the
relationship between the two variables in
which change in the value of one variable due
to change in the value of other variable
6. KINDS OF CORRELATION
• Positive and Negative correlation
• Linear and Non Linear Correlation.
• Simple, Multiple and Partial Correlation.
7. Positive and Negative correlation
When both the variable change in
the same direction, i.e. both the
variables increase or both the
variables decrease, it is called
Positive Correlation
8. POSITIVE CORRELATION
Both Variables increasing
• X Y
• 10 100
• 20 150
• 30 160
• 40 190
• 50 200
• 60 255
Both Variables Decreasing
• X Y
• 70 147
• 60 140
• 40 135
• 30 130
• 15 120
• 10 90
10. Negative Correlation
When both variable change in the
opposite direction, it is called
Negative correlation.
11. NEGATIVE CORRELATION
One Variable increasing and
other Decreasing
• X Y
• 25 125
• 30 110
• 35 90
• 40 80
• 45 75
• 50 60
One variable Decreasing , the
other increasing
• X Y
• 75 110
• 60 180
• 40 190
• 30 300
• 20 240
• 10 250
12. ACTIVITY FOR THE STUDENTS
Please write down: -
(A) 4 example of Positive Correlation
and
(B) 4 examples of negative Correlations
13. Examples of Positive and Negative
Correlation
POSITIVE CORRELATION:-
1. Age of Husband & Age
of wife
2. Price of commodity and
amount of supply.
3. Increase in heat affects
temperature.
4. Increase in height and
weight.
NEGATIVE CORRELATION: -
1. Demand of commodity
may go down a a
result of rise in prices.
2. Sale of woollen
garments and day
temperature.
3. Yield of crops and
price.
14. Linear correlation and Non Linear
Correlation
* If the Ratio of change between two variables is
uniform than Linear correlation exists.
* linear and Non – Linear correlation is based
upon the consistency of the ratio of changes
between the variables.
* Their relationship described by straight line
If the variables under study are graphed, the
point will form a straight line,
15. LINEAR CORRELATION
• In case of non linear relationship , the
amount of change in one variable does not
bear a constant ratio to the amount of change
in the other variable, Such as relationship will
form a curve on graph.
16. Non Linear Correlation
If the ratio of change between the variable is
not the same than Non linear correlation
exists. Non –Linear Relationship will form
curve on graph.
17. Simple Correlation
Simple Correlation : - It is based upon the
number of variable under study.
• When only two variables are studied, the
correlation between them is called simple
Correlation
18. Multiple and Partial Correlation
When three or more variables are
studied the relationship can be
either multiple or partial.
19. DEGREE OF CORRELATION
There is three types of correlations: -
1. Perfect Correlation.
2. Zero Correlation.
3. Limited degree Correlation.
20. PERFECT DEGREE OF CORRELATION: -
• Perfect degree correlation is that where
changes in two variables are exactly
proportional. If equal proportion changes are
in the same direction, there is perfect positive
correlation between the two values described
as + 1,
• If equal proportional changes are in the
reverse direction, there is perfect negative
correlation, described as -1.
21. ZERO DEGREE CORRELATION
• The value of Coefficient of correlation may be
zero. It means that there is zero correlation.
• It does not mean the absence of any type of
relation between the two variables. Two value
are uncorrelated . However, other type of
relation may be there. There is no Linear
relationship between them.
22. LIMITED DEGREE CORRELATION
• In social science , the variables may be correlated, but
an increase in one variable need not always be
accompanied by a corresponding or equal increase (or
decrease) in the variableS.
• Correlation said to be limited positive when there are
unequal's changes in the two variables in the same
direction and correlation degree of combination can be
high ( between + 0.75 to 0.99 and - 0.75 to -0.99)
• Moderate ( + 0.25 to + 0.74 and -0.25 to -0.74)
• Low degree correlation 0 to + 0.24 and 0 to -0.24)
-
25. LIMITED DEGREES OF CORRELATION
HIGH
+ 0.75 TO 0.99
-.075 TO -0.99
MODERATE
+0.25 TO + 0.74
-0.25 TO – 0.74
LOW

0 TO -0.24
