Nov 5, 2023 · When it comes to doing a science project, collecting and recording data is a crucial step in the scientific process. This step involves gathering information and measurements that will be used to analyze and draw conclusions. Here are some tips to help you effectively collect and record data for your science project: 1. Define your variables
- Ask a Question. The scientific method starts when you ask a question about something that you observe: How, What, When, Who, Which, Why, or Where? For a science fair project some teachers require that the question be something you can measure, preferably with a number.
- Do Background Research. Rather than starting from scratch in putting together a plan for answering your question, you want to be a savvy scientist using library and Internet research to help you find the best way to do things and ensure that you don't repeat mistakes from the past.
- Construct a Hypothesis. A hypothesis is an educated guess about how things work. It is an attempt to answer your question with an explanation that can be tested.
- Test Your Hypothesis by Doing an Experiment. Your experiment tests whether your prediction is accurate and thus your hypothesis is supported or not. It is important for your experiment to be a fair test.

Whether it’s a business problem or a personal project that you are working on, a well-defined problem can save you a lot of time and trouble. The objective of a problem statement is to state the problem you are trying to solve clearly. If it is done well, it can be defined in a couple of sentences. Remember your problem statement has to be SMART. 1...
Data collectionis the process of gathering and measuring information on targeted variables of interest in an organised system, which then allows you to answer relevant questions and decide future outcomes. A few examples of data collection methods include: 1. A government institution 2. Kaggle 3. Company database server 4. Self-collected data No ma...
Cleaning your data is a process of ensuring your data is in the correct format; consistent and errors are identified and dealt with appropriately. The actions below lead to a cleaner dataset: 1. Remove duplicate values ( This is usually the case when combining multiple datasets) 2. Remove irrelevant observations (observations need to be specific to...
As the name suggests, during EDA, you get a deeper understanding of the data. During this step, you want to understand your data's statistical characteristics,create visualisations,and test hypothesises. There are four main types of EDA: 1. Univariate non-graphical: make observations of the population and understand sample distributions of a single...
A feature is an attribute of a dataset that is useful to the problem you are solving. If a feature has no impact on the problem you are solving, it is not part of the problem. So what is feature engineering? The better the features you create and choose for your predictive models’, the better your results will be. Feature engineering is an art wher...
All machine learning models are classified either as aSupervised orUnsupervised learning problem. A Supervised problemis where a function maps an input to an output based on input-output pairs. The machine learning model learns from the input-output training data to make predictions on unseen data (test data). An Unsupervised problemis where a mode...
Lastly, it is essential to communicate your results. This can be done through a presentation, formal report or even a blog post. The point is the world has to see the amazing work you have done. A few key points to remember: 1. Don’t overcrowd your slides(6 items max) 2. Use relevant visualisations 3. Know your audience 4. Make sure it flows Data s...
