Manage your time well! Motivate yourself by thinking positive so that you can easily understand the facts presented in the graph. A. CONNECT A.1 Lesson Preview/Review Welcome again to data management. Get ready to learn how to interpret different graphs. Let’s start! Graphs are a common method to visually illustrate relationships in data. The purpose of a graph is to present the data that are too numerous or complicated to describe adequately in the text and with less space. There are plenty of data presented on social media nowadays, make sure you only believe those from reliable sources and always double-check information before you believe it. Remember that sharing personal Data online increases the risk of data cloning, so limit making your information public. B. COACH B.1 Content Notes Topic: Interpreting Different Graphs Reading Comprehension Strategy: Definition and Description In this lesson, you are going to read and learn about how to interpret graphs. To help us understand what we read, we will use the comprehension strategy Definition and Description applied in SAS #06. Instructions: Step 1: Read the content notes carefully to understand the context in which the preselected/underlined words are used.

Imagine you have different tools for different jobs: a hammer for nails, a screwdriver for screws, and so on. Graphs are like tools for showing information. There are many types of graphs, like bar graphs, line graphs, pie charts, histograms, and scatter plots. Each one is good for different things. For example, a bar graph is great for comparing things, like how many students like different colors. A line graph is good for showing how things change over time, like how the temperature changes throughout the day. Histograms are like bar graphs, but they're used to display the distribution of continuous data, like representing the distribution of test scores in a class. Pie charts are about showing parts of a whole, like illustrating the percentage of different genres in a music collection or the breakdown of expenses in a budget. Scatter plots are a way to see if there's a relationship between two variables by plotting points on a graph, like studying the correlation between study time and exam scores. When we pick a graph, we need to think about who will see it and what they need to understand. We also want it to be clear and easy to read, like a book with big letters. So, just like picking the right tool for a job, we pick the right graph to show our information clearly and easily. Step 2: Write the preselected/underlined words in the words column. Step 3: Define the preselected/underlined words by getting the key ideas from the content notes read. Step 4: Write the importance of learning the preselected/underlined words and its use to you as a student or in the future. WORDS DEFINITION IMPORTANCE Graphs A graph is like a visual map made of dots Graphs are like picture maps that show us and lines. The dots represent things, and information in a simpler way and understand the lines show connections between them. things better and make it easier to share information with others. Bar graph A bar graph is a type of graph that uses Bar graphs are important because they help rectangular bars to represent data us see and compare information easily Line graph Line graph is good for showing how things It helps us to understand how things change change over time. over time, helping us spot patterns and trends quickly.

Let’s use again definition and description comprehension strategy step by step for the last content notes. Let’s do this! Understanding Data Ethically When analyzing graphs critically, there are several key concepts to keep in mind, such as data integrity, transparency, fair representation, choosing the right type of graph, respect for privacy and consent, accountability, responsibility, and considering societal impact. First, let's talk about data integrity. It's important to make sure the data in the graph is accurate and reliable. Always verify that the information is correct by asking questions like: Where did the information come from? How was it collected? Is there anything that might make it not true? Next, transparency is essential for ethical interpretation. Graphs should clearly label axes, provide appropriate units, and include necessary context or notes to help us understand them. This makes the information easy to follow and trustworthy. Fair representation means that graphs shouldn't hide anything. They should tell the whole story, not just parts of it. Sometimes people show only parts of the graph to make things seem different than they really are. Always make sure the graph is showing the complete picture.

Graphs come in different forms like bar graphs, line graphs, and pie charts. Each type is good for showing different kinds of information. Pick the one that best represents the data. If a graph looks tricky or doesn't seem right, ask questions! Respect for privacy and consent is crucial. If the graph has information about people or private things, it should keep those secrets safe. Don't show things that could make people feel embarrassed or unsafe. Accountability and responsibility mean always thinking about what the graph means. Ask if it tells the whole story or if something is missing. Make sure you are being honest and responsible with the information. Finally, consider the societal impact. Reflect on how the information in the graph might affect different groups of people or society. By following these steps, we can understand graphs better and make sure we're being fair and honest with the information we see.

This strategy can be used in any subject! It takes practice to do this well. Keep trying! The more you practice, the better you'll get at it. Strategy Review 1. What is the title of the text we read? _______________________________________________________________________________ 2. What reading comprehension strategy did we use? _______________________________________________________________________________ 3. What are the four steps in this strategy? _______________________________________________________________________________ B.2 Skill Building Activity Activity B.2.1 Drawing out information from graphs involves several steps to ensure clarity and accuracy. Here's a step-by-step process you can follow: Step 1. Identify the type of graph. Is it a line graph, bar graph, pie chart, scatter plot, etc.? Each type of graph represents data differently. Step 2. Look at the Lines and Labels. Pay attention to the lines (like the lines going across or up and down) and the labels (words) on the bottom and side of the graph. They tell you what the graph is about and what the numbers mean. (x-axis: horizontal and y-axis: vertical) Step 3. Read the Title. The big title at the top of the graph usually tells you what the graph is showing. Step 4. Find Patterns. Identify patterns or trends in the graph. For example, are the lines going up, down, or staying the same? increasing or decreasing trends. Step 5. Do Math if Needed: Sometimes you might need to do a little bit of math to figure out more about the graph, like finding averages or percentages. Step 6. Consider Context: Think about the broader context of the data. Understanding the context helps in drawing accurate conclusions. Step 7. Check for Outliers or Anomalies. Check if there are any numbers or points on the graph that seem different from the others. These could be important, or they might be mistakes. Step 8. Summarize Findings. Finally, talk about what you found out from the graph. Describe what it's showing and what you think it means Learning Modules by PHINMA Education is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License.  MAT 152: Mathematics in the Modern World Module #7 Name: _________________________________________________________________ Class number: _______ Section: ____________ Schedule: ________________________________________ Date: ________________ Example: Draw out information from the given graph below using the step-by-step process. Step 1. Identify the type of graph. It is a line graph comparing the number of vehicles manufactured by two companies, A and B, over a period from 1997 to 2002. Step 2. Look at the Lines and Labels. x-axis (horizontal): Represents the years from 1997 to 2002. y-axis (vertical): Shows the number of vehicles manufactured in thousands. Lines: Company A and Company B. Step 3. Read the Title. The title is "Number of Vehicles Manufactured by Two Companies From 1997 to 2002 (in Thousands)". Step 4. Find Patterns. Company A: Starts at 119, decreases to 99 in 1998. Peaks at 141 in 1999, then drops to 78 in 2000, then rises smoothly from 120 in 2001 to 159 in 2002. Company B: Starts at 139, decreases to 120 in 1998. Falls at 120 to 100 in 1999, peaks at 128 in 2000. Drops to 107 in 2001, then increases to 148 in 2002. Step 5. Do Math if Needed. Averages: Calculating the average production over the years could provide additional insight. Company A: (119 + 99 + 141 + 78 + 120 + 159) / 6 ≈ Approximately 120,000 vehicles. Company B: (139 + 120 + 100 + 128 + 107 + 148) / 6 ≈ Approximately 124,000 vehicles.

Consider Context. The graph shows trends in vehicle manufacturing over six years. Maybe they had new models, changes in management, or economic issues. Step 7. Check for Outliers or Anomalies. Company A made a lot fewer vehicles in 2001 (78,000) than in other years and both companies made a lot more vehicles in 2002. Step 8. Summarize Findings. Company A experienced significant fluctuations in production, with a notable drop in 2001 and a dramatic increase in 2002 and Company B had more stable production numbers but also saw a significant increase in 2002. Both companies showed a positive trend in vehicle manufacturing by the end of the period, especially in 2002. Conclusion: Company A had big changes in the number of vehicles they made each year, especially in 2001 and 2002 and Company B was steadier but also made a lot more vehicles in 2002. Something important might have happened in 2002 that made both companies increase their production. By following these steps, you can understand and explain the information in the graph.
