wunder beta📊 Pictographs and Tally Charts
Collect data and show it off — read and build pictographs, tally charts, and tables, and pick up the real vocabulary of data along the way.
What you’ll learn
- Tally ChartsRead and build a tally chart, using bundles of five, and read off the frequency.A tally chart records one mark for each thing counted, grouped into bundles of five — four lines with a fifth crossing them. Counting the bundles gives the frequency, how many were counted in each category.
- PictographsRead and construct a pictograph where each symbol represents one item.A pictograph uses pictures to show amounts, with each symbol standing for one item. You read it by counting the pictures in a row — the longest row is the biggest group — and you build one by drawing one picture per item counted.
- Data WordsUse the vocabulary of data: data, survey, frequency, category, title, axis, scale, and label.Data work has its own words. Data is the facts collected, a survey gathers them by asking a question, and frequency is how many times something is chosen. Good charts also have a title, labeled axes, and a scale so anyone can read them.
- Discrete or ContinuousDistinguish discrete data (counted) from continuous data (measured) with examples.Discrete data is counted in whole numbers, like the number of pets or books. Continuous data is measured with a tool like a ruler, scale, or clock, such as a plant's height or a puppy's weight. Knowing the difference helps you choose the right chart.
Questions this course answers
In a tally chart, how many does one full bundle stand for?
A bundle is four lines with a fifth crossing them — five in all.
A pet survey shows Dog with 7 tallies and Cat with 5. Which has the higher frequency?
Frequency is the count; 7 is more than 5, so Dog is higher.
In a pictograph where each picture means one item, a row has 6 apple pictures. How many apples?
Each picture stands for one, so 6 pictures means 6 apples.
On a pictograph, which row shows the MOST?
More pictures means more of that thing, so the longest row is the most.
What do we call asking a group the same question to gather data?
A survey is asking people a question to collect data.
What does a chart's TITLE tell you?
The title states what the chart is about.
