“Data processing” in statistics is an important concept that ensures the integrity of research data as it considers important concerns such as security, confidentiality, and storage of research data. Each domain has information in the form of numbers. Any number of this type is called an observation. In general, the collection of all observations is called data. To process data, statisticians use various data management methods. In this article, we explain what data processing is and the different ways in which data processing can take place.

What is Data Handaling?

Data handling is, Handling the data in such a way that it becomes easier for people to understand and comprehend the given information. Kids have difficulty understanding and processing data. In most cases, these learners have gaps in their general mathematical understanding that may prevent them from understanding how to process data activities.

While learning data handling kids may struggle because of:

• Poor numeracy skills.
• Lack of strategies and alternative approaches.
• Data is not in a context that makes sense to them.
• No connection with everyday examples.
• Lack of resources to help them understand.

In this article, we will learn about various ways in which one can represent data so that kids may easily understand the same.

Bar Graph Representation

A bar graph, also known as a bar chart, is a visual representation of data using rectangular bars of varying lengths. Each bar represents a category, and the length of the bar corresponds to the value or frequency of that category. Bar graphs are excellent for comparing discrete data across different groups or categories.

They typically have two axes: a horizontal axis (x-axis) showing the categories being compared, and a vertical axis (y-axis) representing the measured values. Bar graphs can be vertical (column charts) or horizontal, and are widely used due to their simplicity and effectiveness in displaying categorical data.

Scatter Plot Representation

A scatter plot, also called a scatter diagram or scattergram, is a type of graph used to display the relationship between two continuous variables. It plots individual data points on a two-dimensional graph, where each point represents an observation with two values – one for each variable.

The x-axis typically represents the independent variable, while the y-axis represents the dependent variable. Scatter plots are particularly useful for identifying patterns, trends, correlations, or clusters within data sets. They can reveal whether there’s a positive, negative, or no correlation between variables, and can also highlight outliers or unusual data points. Scatter plots are commonly used in statistics, scientific research, and data analysis to visualize and interpret relationships between variables.

Games to Teach Data Handling to Kids

One can ask kids to play various games related to data handling that helps them to learn the basic of data handling and improve their learning skills. various games related to same are:

• Survey and Graph It: Have kids conduct simple surveys among classmates on topics like favorite colors, pets, or ice cream flavors. Then help them create bar graphs or pictographs to represent the data.

• Dice Roll Statistics: Kids roll dice multiple times, recording results and creating frequency tables. This introduces concepts of data collection and representation.

• Weather Tracking: Set up a simple weather station to record daily temperature, rainfall, or cloud cover. Kids can then plot this data over time.

• Sorting Games: Use items like buttons, candies, or toy cars to practice sorting by different attributes (color, size, shape) and counting the groups.

• Data Scavenger Hunt: Create a list of data-related items for kids to find in magazines or newspapers, like a pie chart or a mean (average) value.

• Probability Experiments: Use spinners or colored balls in a bag to conduct simple probability experiments and record outcomes.

• Human Bar Graph: Have kids physically line up to create a living bar graph based on categories like hair color or favorite subject.

• Guess the Jelly Beans: Fill a jar with jelly beans and have kids estimate the number. Record guesses and compare to the actual count.

• Data Card Games: Create cards with different data representations (tables, graphs) and play matching or “Go Fish” style games.

• Online Data Games: Many educational websites offer interactive games that teach data handling concepts in fun, engaging ways.

Interesting Ways to Teach Data Handling

Types of Graphic Representation in Data Processing: When dealing with data, there are various ways to visually represent information using diagrams. Data can be represented graphically in the following ways:

• Pictogram
• Pie Chart
• Line Chart

Pictogram

A type of graph called a pictogram, uses images, icons or symbols to represent data. It is the easiest way to represent information in statistics and data processing. Pictograms make data much easier to interpret, especially when a lot of information needs to be represented.

Pie Chart

Imagine plotting your data in a beautiful circular chart called a pie chart. This diagram has different sections, like slices of a pie, each of which represents a particular piece of information. Pie charts are great for showing profit and loss for a company, numbers in schools, marketing, sales, etc.

Line Chart

A special type of chart is used in data processing called a line chart, which is very useful for showing how things change over time or under different circumstances. A line chart is created by connecting the points on the chart with a line. Each dot represents a specific data point.

Teaching Ideas/Activities

Demonstrate the importance of keeping the pictures/symbols the same size, cut out square pieces of paper or card in the following sizes 3cm x 3cm, 7cm x 7cm and 10cm x 10cm. You will need enough squares so that learners have one square each (some will have a 3 cm², others a 7 cm² and others a 10 cm² square)

• Ask a simple question which you think will have a varied but limited number of answers, e.g. “How did you get here today?” (Walk/Bus/Car/Bike)
• Mark simple axes on the board, and the words (Walk/Bus/Car/Bike) below.
• Invite the learners to place their square above their answer (Fixing with blu-tack).
• Once everyone has given their answer, discuss whether the pictogram shows a fair picture.
• Does it matter that the squares are not the same size?
• Demonstrate that it is not necessarily the ‘tallest column of pictures’

Conclusion

Infographics are visual representations of information that combine text, images, charts, and graphs. They combine compelling data and statistics with visually appealing elements to make data more understandable and engaging. Infographics can explain concepts, make boring topics interesting, and tell a story. When tackling a seemingly boring subject, try applying these seven characteristics: simplicity, surprise, specificity, believability, emotion, storytelling, and precision. These elements can make even the most mundane commercials memorable.

FAQs

Define Data Handling

Data handling means collecting the set of data and presenting in a different form. Data is a collection of numerical figures that represents a particular kind of information. The collection of observations which are gathered initially is called the raw data. Data can be in any form.

Why is teaching Data Handling Important?

Teaching kids data handling can help them make sense of information and recognise patterns more easily. Data processing can be split into four steps in maths. These steps are: Collecting data.

3).What are Advantages of Data Handling?

Data handling allows children to make sense of information, to identify patterns and trends and to predict and plan for the future (Griffiths, 2001). As pre-service teachers we find the topic of data handling to be a integral part of children’s mathematical understanding.

4).What are Uses of Data Handling?

In healthcare, it helps manage patient records and do medical research. Schools use it for grading students and managing tasks. It is also important to keep information safe online. It helps in many areas to make good choices and work better.
