Today is a special day at my school because we’re having our own mini Olympics! Schools from all over the state are coming to join us. I’m super excited because I love sports, and I get to be one of the officials. My job is to watch the events and help record the results. We will be collecting a lot of data today.
Data is a fancy word for information. It can be anything we observe or measure. For example, data can be words, like the names of the schools that are participating or the names of the different events. It can also be numbers, like how high someone jumps in the high jump, the fastest time in a race, or how many medals each school wins.
Before the competition starts, I will collect some data about the participants. One way to collect data is by using a survey. A survey is a list of questions we ask people to gather information. Another name for a survey is a questionnaire. When making a survey, it’s important to think carefully about the questions you want to ask and how many people will answer them.
Some questions might have simple answers, like “Which event are you competing in today?” I can record answers to this question by checking a box. For other questions, like “How many days a week do you train?” I need to make sure the answer choices cover all possibilities and don’t overlap. Some questions might be open-ended, like “What are you most looking forward to about today?” For these, I will write down what each person says.
Now that everyone is here, it’s time to start the events. I’m going to the track to record data from the long jump competition. I will use a recording sheet, which is a special paper for writing down the data as I collect it. My recording sheet has each competitor’s name in the first column and space in the next three columns to record how far they jump in each of their tries. If they step over the line, I will mark that instead of writing a distance. Once the competition is over, I can find the longest distance jumped by each competitor and write it in the last column. Then, I can figure out who the winner is.
There’s a lot more data to be collected today. It’s going to be a fantastic day!

Create Your Own Survey: Think about a topic you are interested in, like favorite fruits or pets. Create a simple survey with 3-5 questions. Ask your family or friends to answer your survey. Once you have collected the data, make a chart or graph to show the results. What did you learn from your survey?
Data Detective: Go on a data hunt around your home or school. Look for things you can count or measure, like the number of books on a shelf, the height of plants, or the colors of cars in a parking lot. Record your findings in a notebook. Can you find a way to organize your data, like making a list or a table?
Observation Journal: Choose a spot in your garden or a park and observe it for a week. Each day, write down what you see, like the number of birds or changes in the weather. At the end of the week, look at your notes. What patterns do you notice? How did the data change over time?

Today, my school is hosting our own mini Olympics. Schools from all over the state are coming to participate. I’m really excited because I love sports, and I will also be one of the officials. I will watch the events and help record the results. We will collect a lot of data today.
Data is a general term for information, such as observations or measurements, and we can collect data on various topics. Data can be words, like the names of the schools participating or the names of the different events, or it can be numbers, such as the heights jumped in a high jump competition, the winning time in a race, or how many medals each school has won.
Before the competition starts, I will collect some data about the participants. One way to collect data is by conducting a survey. A survey is a set of questions we ask people to gather information. Another term for a survey is a questionnaire. When designing a survey, it’s important to think carefully about the questions you want to ask and how many people will respond.
Some questions might fit easily into categories, such as “Which event are you competing in today?” I can record responses to this question by checking a box. For other questions, like “How many days a week do you train?” I need to ensure the response options cover all possibilities and do not overlap. Some questions might be open-ended, like “What are you most looking forward to about today?” For these, I will write down what each person says.
Now that everyone is here, it’s time to start. I’m heading over to the track to record data from the long jump competition. I will use a recording sheet, which is a template for writing down the data as I collect it. My recording sheet has each competitor’s name in the first column and space in the next three columns to record how far they jump in each of their attempts. If they step over the line, I will mark that instead of recording a distance. Once the competition is over, I can find the longest distance jumped by each competitor and write it in the final column. Then, I can determine who the winner is.
There’s a lot more data to be collected today. It’s going to be a great day!
