Chemistry IBDP is one of the six group 4 Sciences of the IB curriculum. The IBDP Chemistry program explores the three important aspects of chemistry: Physical, Organic, and Inorganic chemistry. The program requires the student to take a look at the qualitative and quantitative aspects of each of the sections using a range of techniques. These techniques range from informative theoretical knowledge to practical applications in the lab and the real world.

This holistic approach allows students to learn in a variety of methods including but not limited to exploration, discovery, gathering and interpreting data, analysing outcomes, and giving feedback. The IBO’s special attention to criteria ensures that the student can interconnect the subjects they have chosen and be able to apply them in real life.

In this chapter of IBDP Chemistry, we take an in-depth look at the concept of Measurement and Data Processing and Analysis. The chapter can be divided into four sections, all of which are covered comprehensively in our notes. We begin with uncertainties and errors that is encountered during the measurement of data- . In addition to this, we will also be taking a close look at differences between precision and accuracy, the importance of significant figures, and a comparison between random and systematic errors.

Our next section focuses on important techniques used in graphs. We cover the basics such as calculating the gradient and the intercept c within the equation of a line and also what a line of “best-fit” is. Our final section explores techniques used in organic chemistry. These detailed discussions cover Index of Hydrogen Deficiency (IHD) and Mass, Hydrogen nuclear magnetic resonance, and infrared spectroscopy which is further elaborated using guidelines to help effectively apply them in exam-style style questions. We also take a look at the Electromagnetic Spectrum and X-ray crystallography.

At the end of this chapter, we can expect the students to be able to effectively use numerical data in theory and use their knowledge of measurement and analysis to process data throughout their IBDP career and beyond.
