What is a Trendline and Why Is It Useful?

Before we jump into the "how," let's quickly cover the "what" and "why." A trendline, also known as a line of best fit, is a line added to a chart or graph that reveals the overall direction or pattern of your data over time or across categories. It cuts through the noise of individual data points to show whether your key metrics are generally increasing, decreasing, or remaining stable.

Think of it as the big-picture story your numbers are trying to tell. If you're looking at monthly sales figures, the numbers might bounce up and down. A trendline smooths out those bumps to show if your sales are fundamentally growing, slumping, or flattening out for the quarter.

Here's why they are so valuable for data analysis, even when you're working from an iPad:

• Identifying Patterns: Are website visits slowly climbing month-over-month? Is customer churn gradually decreasing? A trendline makes these patterns instantly visible.
• Forecasting Future Performance: By extending the trendline, you can make educated guesses or forecasts about where your data might be headed. This is great for setting future goals or anticipating challenges.
• Simplifying Complex Data: Instead of getting lost in a hundred individual data points on a scatter plot, a trendline gives you a single, clear summary of the relationship between variables.
• Making Data-Driven Decisions on the Go: Being able to quickly add a trendline from your iPad allows you to spot important business insights from anywhere - whether you're in a meeting, traveling, or just away from your desk.

Preparing Your Data for a Chart

Before you can add a trendline, you first need a chart, and before you create a chart, your data needs to be organized properly. Google Sheets creates charts most easily from simple, two-column data sets.

For a trendline to make sense, one of your columns should represent a progression, like time (days, months, years), and the other column should contain your quantitative data (sales, users, clicks, etc.).

Let's use a simple example: tracking website traffic over six months.

Your data in Google Sheets should look clean and simple, like this:

• Column A: Month (e.g., January, February, March)
• Column B: Website Clicks (e.g., 5200, 5500, 6100)

Ensure there are no blank rows or columns in the middle of your data range, as this can confuse Google Sheets when it tries to generate a chart automatically. With your data properly structured, you're ready to create your chart.

How to Add a Trendline in Google Sheets on Your iPad: Step-by-Step

The process on an iPad involves a few taps and navigating through the app's menus. Don't worry, it's straightforward once you know where to look. We'll use a line chart for this walkthrough, as it's a common choice for visualizing data over time.

Step 1: Create Your Chart

First, we need to create the visual your trendline will live on.

1. Select Your Data: Tap on the first cell of your data (e.g., A1), then drag the blue corner handle to highlight all the data you want to include in your chart.
2. Insert the Chart: With your data selected, tap the "+" icon at the top of the screen. A dropdown menu will appear.
3. Choose 'Chart': From the menu, select "Chart". Google Sheets will automatically analyze your data and suggest a chart type. Most of the time, it will suggest a good starting point, like a line chart or a column chart.

Once you tap 'Chart', your data will be instantly visualized in a new chart floating on your spreadsheet view. The default for our monthly clicks example will likely be a nice, clean line chart. Now, let's add the trendline. If for any reason, Google Sheets suggests the wrong format for the chart type, and you wish to change it manually, simply double-tap on it, then press ‘Type’ to make your amendments. For this exercise, we would be selecting the Line chart type.

Step 2: Access the Chart Customization Menu

With your chart created and selected, you can access the options to customize it, including adding a trendline.

1. Edit the Chart: Double-tap anywhere on the chart object you just created. This action opens the "Chart editor" menu.
2. Find the Customization Screen: The chart editor has several sections. Use your finger to scroll down the "Chart editor" menu until you pass the ‘Legend’ and the ‘X-axis’, and ‘Vertical Axis’ menu. The last menu item will be the "Series" menu. Tap on that to view the customizations and add your trendline here.

Step 3: Add and Customize the Trendline

This is where you'll find the magic button. Once you get to this screen, it has some basic toggle switch customizations based on what is available and practical to activate on an iPad as opposed to the desktop version of Google Sheets.

1. Turn on the Trendline: In the "Series" menu options, you'll find different customizations you can apply to the main data points. Here is where the "Trendline" toggle switch is. Turn it on — Voila! A trendline should immediately appear on your chart.
2. Choose Your Trendline Type: Google Sheets offers several types of trendlines for different kinds of data analysis. While the iPad app is slightly more limited than the desktop version, it still provides the essentials an on-the-go user needs to analyze data.
3. Change the Trendline Color: Below the "Type" menu, you will find a basic color picker menu where you can amend the basic look of your graph by clicking on its different default theme colors. Pick a color that stands out but isn't distracting, like red or dark grey. Simple! Click and exit.

And that's it! You now have a trendline on your Google Sheets chart right on your iPad. Simply exit the menu and all your changes will be saved.

Types of Trendlines Available on iPad (and What They Mean)

The Google Sheets mobile app might give you slightly fewer options than its web-based counterpart, but the most important ones for every business user are there with a few taps or, in this case, swipes. Depending on the version, it might not give all the desktop version's trendlines, like "Moving Average," but every iPad will have the following options.

• Linear: This is a straight line and is one of the most commonly used trendlines. A Linear trendline shows a steady rate of increase or decrease for your data. Use it when your data points resemble a straight upward or downward line. For our example, it is ideal when analyzing steady growth in sales or a slow decline in daily web traffic because the straight line is good for highlighting trends.
• Exponential: This results in a curved line that showcases data values that rise with compounding value. Use it with data that has large increases in volume, like population rise, or to illustrate the snowball effect in viral marketing campaigns. If your data is growing fast, skip Linear and use this one to tell the true story of your business in one view!
• Polynomial: Need to analyze large data sets that can fluctuate a lot? A polynomial trendline effectively illustrates these undulations with its curve that can change direction. It's useful when data cycles upwards and downwards, such as monthly revenue with seasonal highs and lows. Think of a hotel's booking data over a year, where different seasons show varying trends.

Interpreting Your New Trendline

Now that you've added the trendline, all you need is to know how to interpret it to make a big-picture analysis of what the story behind the numbers is.

• An Upward Sloping Trend: A Great Sign! A positive trend indicates growth, showing that the upward slope in your data points outperforms downward periods. This suggests that something is working well in your strategy and marketing campaigns. If a website has had consistent visits over months, despite minor dips, it proves resilience and success.
• Flat or Downward Sloping Trend: A Call to Action A flat, straight line with little slope indicates stability or stagnation. While stability isn't always bad, it might mean something is not responding in the current campaign. When a website's traffic plateaus, it's crucial to investigate what may be affecting performance and work on preventing further decline. If there's a negative slope, it shows where KPIs are dropping, allowing for quick diagnosis and action to mitigate potential damage.

Troubleshooting Common Issues

Sometimes things don't go as planned. Here are some solutions to hurdles you might face when adding trendlines on your iPad.

"I Can’t Find the Trendline Option"

If you've reached the 'Series' menu and don't see it, the likely issue could be your choice of chart. Trendlines generally cannot be applied to every type. Charts like stacked area or pie do not support trendlines as they are designed for visualizing parts of a whole.

To ensure your trendline analysis is correctly visualized, try switching to a line, column, or scatter chart, as those will work and show the button you are looking for.

"The Trendline Looks Misleading"

Choose your trendline type based on understanding your data's story best. AI may still misinterpret which trendline fits, so make sure you select the correct type yourself. For example, using an exponential curve is not appropriate for straightforward data that's better suited to linear trends. Choose Polynomial for data that fluctuates with seasons or cycles, ensuring that the message is complete and accurate.

"The App is Lagging Creating a Chart"

If working with large volumes of data, the Google Sheets app may start lagging on your device. This can occur due to the processing demands of handling extensive spreadsheets, not just on mobile but also on less powerful computers. To work around this, pre-prepare some charts and save a clean template for quick import, speeding up the process significantly.
