This document is a chapter summary covering key topics in analyzing scientific data, including units and measurements, scientific notation, uncertainty in data, and representing data graphically. It discusses the SI system of units, derived vs base units, accuracy vs precision, significant figures, error analysis, and types of graphs like line graphs, bar graphs and pie charts. Key points covered include the SI base units, dimensional analysis using conversion factors, expressing numbers in scientific notation, and interpreting graphs to identify patterns and trends in data.
The results of an experiment can be presented as a data table or as an equation that represents them. In the case of adjusting a polynomial, Excel allows us to change its degree and calculates the R2 of the adjusted equation. It is considered that if it is 1 the equation goes through all the experimental points. By adjusting Tungsten resistivity data, it is found that the equations do not go through all the points (even with R2 = 1), which is verified by calculating the differences for each point. In those cases, the best fit is the linear interpolation between consecutive points. The equation adjusted by Excel, Matlab or Origin requires checking if it corresponds to the minimum in the sum of squared differences, it is possible that it can be reduced by changing the coefficients values.
Basic Understanding of measurement errors, its definitions, types and few examples are discussed with pictures, block diagrams etc. Totally suitable for the learners of engineering and science fields.
I split the presentation for the unit into two, as I added so many slides to help with student questions and misconceptions. This one focuses on mathematical aspects of the unit.

Data mind traps are when we use a quantitative method that does not fit the data structure. As a result, we derive the wrong conclusion. This presentation uncovers four data mind traps related to testing many hypotheses, assuming data is normally distributed, confusing statistically significant with material, and dealing with causation.
Experiment #1 in Instrumentation And Dynamic Systems Lab : Calibration Osaid Qasim
Calibration experiment :
1- Calibrate analog multimeter using digital multimeter in DC scale.
2- Calibrate analog multimeter using digital multimeter in AC scale.
3-Calibrate the positive gauge pressure using dead weight calibrator
4- Calibrate negative gauge pressure by using a U manometer
Digital computer deals with numbers; it is essential to know what kind of numbers can be handled most easily when using these machines. We accustomed to work primarily with the decimal number system for numerical calculations, but there is some number of systems that are far better suited to the capabilities of digital computers. And there is a number system used to represents numerical data when using the computer.

Instructions for Submissions thorugh G- Classroom.pptxJheel Barad
This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
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.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
