9-10 Digital Technologies: Analysing and visualising data Hangman
Years 9–10 · Victorian Curriculum · 16 key terms.
Every word, shuffled.
The names stay in this browser on this computer — they are never sent to Cloodit. A random student is called for each word.
Students use charts, trendlines, pivot tables, interactive filters and SQL summaries to find trends and outliers, draw careful conclusions and make predictions. See the whole journey →

The 16 key terms
- 1pattern, trend, outlier
- Look for patterns and trends in data, like highest, lowest, going up or down. An outlier is a value that stands out from the rest. Compare groups to see differences.
- 2Choosing the right chart
- Pick the chart that matches your question: a bar chart to compare categories, a line chart for change over time, and a pie chart for parts of a whole.
- 3bar chart
- A chart that uses bars to compare amounts in different categories. Select the labels and values, then choose Insert chart. Column charts have upright bars; bar charts lie sideways.
- 4line chart
- A chart that joins points with a line to show how a value changes over time. Time goes along the bottom axis, so you can see if the trend goes up or down.
- 5scatter plot
- A chart with one dot per record, using two numeric fields as x and y. The cloud of dots shows if the variables are related, and a dot far from the rest is an outlier.
- 6Title, axis labels and legend
- The parts that help a viewer read a chart: the title says the topic, axis labels name the data and units, the legend explains colours.
- 7trendline
- A line fitted through a chart's points that shows the overall direction of the data. A chart tool can add one with its equation, and the R-squared value shows how well it fits.
- 8=FORECAST(x, known_ys, known_xs)
- Estimates a new y value for a given x by extending the trend of existing data, e.g. predicting next year's sales. It is less reliable the further x is beyond the known data.
- 9pivot table
- A tool that summarises a big table by grouping rows under row and column fields, then working out a sum, count or average for each group. Refresh it when the data changes.
- 10slicer
- A set of buttons linked to a table, pivot table or chart. Click a button to filter the data, so a viewer can explore it interactively. Clear the filter to show everything again.
- 11Conditional formatting
- A spreadsheet tool that changes a cell's colour or icon automatically when its value meets a rule, so highs, lows and outliers stand out.
- 12SELECT AVG(score) FROM results;
- An aggregate function works out one value from many rows. COUNT, SUM, AVG, MIN and MAX give the count, total, mean, lowest and highest. This query returns the mean score.
- 13GROUP BY
- An SQL clause that sorts rows into groups sharing the same field value, then applies an aggregate like AVG or COUNT to each group, giving one result row per group (e.g. average score per class).
- 14correlation is not causation
- Two things can rise or fall together without one causing the other. A trend shows a relationship, not the reason, so a hidden third factor may explain both.
- 15conclusion
- A statement that answers a question using evidence from the data, such as numbers. It should only say what the data shows and stay within the data's limits.
- 16reliability
- How much you can trust a prediction. It drops with small samples, outliers and predicting far beyond your data, so always state how uncertain the prediction is.
Frequently Asked Questions
Do I need an account?
No. Hangman runs straight from this page — no account, no sign-up, nothing to install. If you add your class names, they are saved in your own browser and never sent to Cloodit.
How do I play it with my class?
Put the page on your whiteboard or projector and press Play. The class calls out letters and you click or type them. Six wrong letters and the word gets away. After every word its definition appears, so each round ends on the meaning, not just the spelling.
Can I use my own words?
Yes. The free Hangman generator at cloodit.com/hangman/ takes any list: one word or phrase per line, with a definition after a dash if you want it shown at the end of the round.
Can I put my students' names in?
Yes. Add your class list and a random student is called for each word. The list stays in this browser on this computer, so it is still there next lesson.
Are the worksheets free too?
Yes. Every module in this journey has a free printable worksheet with a full answer key, and there are crosswords and word searches built from the same key terms.
