I have to write an essay, but I don't know where to start! Got same problem?

No, I know what to write!

Oh, yeah!

Chemistry as a subject has a significant importance in our daily lives and society in general. Everything on the earth is made of chemicals. Chemistry helps us understand how items around us are made e. g cooking gas. In our daily life, we fall sick and consequently need drugs that are made by scientists through chemistry. This helps to know what drugs to take by showing their contents and their impacts on our bodies. (Lagowski, J. J, 1991).

Through chemistry, we get to understand how food gives energy to our bodies; this enables us to be careful regarding contaminations and also their consequences afterward such as diseases. Chemistry helps to understand and observe the changes around us since such changes are caused by chemistry, for example, changes in the colors of leaves.

It helps in day-to-day decisions that affect our lives e.g. mixing household chemicals such as tea leaves and sugar. It also describes various chemical elements present in the environment, their reactions, and their effects on the environment. It illustrates environment segments, their interrelationships, and their significance.

In our daily lives, we wear clothes that are made of fabrics such as nylon which is learned in chemistry. It also boosts the industry sector through the extraction of valuable metals such as copper, zinc, and magnesium and also helps in understanding the chemical reactions of such metals. We use soaps that are made through a process called saponification in chemistry, these soaps help in carrying out daily activities such as laundry.

Difference between Accuracy and Precision

Accuracy is termed as the degree of veracity, it describes the closeness to the target. The closeness of the measurement to the target makes a system to be around 98 accurate and vice versa. Accuracy is how correctly a test identifies or excludes a condition. It also means that the measured values are the same as the given value; it is also determined by sensitivity.

Precision is the degree of reproducibility.

Refutability is the variation that arises when all efforts are made to keep conditions constant by using the same instruments and operators and repeating during a short period.

Reproducibility is the variation arising when all efforts are made through having all required measurements of all different instruments by using given operators over a longer period. It is the ratio of true positives to the sum of all positives(true positives and false positives).

Explaining How Society Depends On Accuracy and Precision

Society, in general, depends on accuracy and precision in many ways. In society, there exist media organizations. Accuracy and precision are of great use here since the media should enhance them.

Reliability is presenting strongly evidenced, examined, and tested unambiguous information for it to be accurate. It must have verified facts, not rumors or speculation. Society, therefore, uses accuracy to rate the media organizations. The society comprises organizations and institutions which keep records and notes. Such records and notes need accuracy for the organizations and institutions to be reliable and contemporaneous. Such accurate records help organizations make wise decisions.

Accuracy and precision determine the kind of relationships people will have in society. What we say is reflected in us. If we are accurate, people will have confidence in the veracity of our statements thus relating well and boosting togetherness in society.

Comparison and Contrast of Accuracy And Precision Used in 3 Types Of Measures in Life

  1. Binary Classification

Accuracy here can be employed as a statistical measure of how well a binary classification test correctly identifies and classifies a condition. Accuracy is known to be the ratio of the number of true positives + the number of true negatives, calculating the number of all true positives and adding all false negatives and also true negatives will give precision which means the number of true positives or the number of true positives + false positives.

  1. Target Analogy

Any accuracy in a real sense demonstrates the closeness of any arrow to a given target center. Arrows that are closer to the bull’s eye are more accurate. It means that the measurement is rather close to the given value ( David Garner).

Precision includes larger numbers of arrows being shot, and it is the cluster’s size. When the arrows are set in one area, the calculated cluster is generally referred to as precise because they are always stuck together although not to the given target.

  1. Quantification

The measurement precision and accuracy is usually a process established by repeated measuring the same reference standard. It is maintained and done by the national organizations of standards. It is applied when the same measurements are averaged and repeated. In this case, the common error is usually applied. When calculating the average precision of any matter, it is said that average precision is the same as a given standard (SD) and through division using the squire root of any given measurement.


Using accuracy, it is possible to establish the difference between the reference value and the mean of the measurement. Correcting and establishing the bias is a necessary thing for calibration as well as the combined effect of aid precision. Precision (repeatability) is the variation arising when all efforts are made to keep conditions by using the same instrument and operators over a long period.
