This document defines and provides examples for calculating the mode of data sets. It explains that the mode is the value that occurs most frequently in a data set. For ungrouped data, the mode is simply the value that repeats the most. For grouped data, formulas are provided to calculate the mode using the median, mean, class intervals and frequencies. Examples are given to demonstrate calculating the mode for grouped data. The document also lists some merits and shortcomings of the mode as a measure of central tendency.
students will be able to understand various measures of central tendency and also will be able to calculate mean median and mode for individual discrete and continuous series.

One of the three points that divide a data set into four equal parts. Or the values that divide data into quarters. Each group contains equal number of observations or data. Median acts as base for calculation of quartile.
Introduction to Mode.
Calculation of modes by different methods.
Merits and Demerits of Mode.
Mode is the value which occurs the maximum number of times in a series of observations and has the highest frequency.
Calculation of Mode
1. Calculation of mode in a series of individual observations (Ungrouped data)
2. Calculation of mode in a discrete series (Grouped data)
3. Calculation of mode in a continuous series (Grouped data)
4. Calculation of mode in a unequal class intervals (Grouped data)
The standard deviation is a measure of the spread of scores within a set of data. Usually, we are interested in the standard deviation of a population.
Measures of Central Tendency
Requirements of good measures of central tendency
mean, median, mode
skewness of distribution
relation between mean, median,mode

Embracing GenAI - A Strategic ImperativePeter 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.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

3. MEANING OF MODE
Mode is defined as the
size of a variable which
occurs most frequently
4. COMPUTATION OF UN
GROUPED DATA
25,29,24,25,27,25,28,25
Here 25 is repeated maximum number
of times there for mode=25
5. Computation of mode
for grouped data
Mode = 3Median-2Mean
Mean = 44.6,Median=44.05
Calculate mode
Mode=3*44.05-2*44.6
mode=42.95
6. Another method for
grouped data
Mode=L+f1∕f1+f2
L=Lower class of model class
i=class interval
f1=frequency of the class adjacent to the model class for
which lower limit is greater than that for the model class
F2=frequency of the class adjacent to the model class
8. The crude mode is lie with in the class interval
20-25 Hence
L=20 f1=4
i=5 f2=5 therefore
M0 = 20+4/4+5*5
= 20+4/9*5
= 20+2.22
= 22.22
9. MERITS
It is an average widely used in every day life. When
we speak of average, we generally refer mode
It is very easily under stood and determined. it can be
determined by inspection alone
It encourages attention to binomial and multimodal
data
It is useful in the situations in which it is desirable to
eliminate extreme cases.
To ordinary mind, it appears best to represent to
group.
10. SHORT COMINGS
It is not at all reliable in small samples for example , if
model salaries of 50 workers aer Rs 100 per month , bt
45 out of them get different salaries , the mode is very
unreal and gives a false picture.
It is incapable of algebric treatment .mode of one
distribution can’t be combined with another to give a
combined mode.
In many cases, one single well defined mode exists.
