Get ReadyPrepárate
Wake up what you know, then explore today's model.
Activa lo que sabes y luego explora el modelo de hoy.
- Group 8 arcade scores into intervals of width 5. Predict which interval will have the greatest frequency. Then move one value across an interval boundary in the model and say which bars change and which stay the same.
- Which of these is a statistical question?
- How many minutes are in one hour?
- How many days are in September?
- How many sides does a hexagon have?
- How many minutes did each student read last night?
- 'How tall is our flagpole?' is NOT a statistical question. Why not?
- It is about height
- It uses numbers
- It has only one answer, so there is no variability
- It is only asked once
- A class collects this data on pets owned: 0, 2, 1, 0, 3. Which statistical question could these answers come from?
- How many students are in the class?
- What is the largest number of pets allowed?
- How many pets are in the store?
- How many pets does each student own?
- 1 fresh problem with new numbers each time (interactive only).

Use the hints when you need them. Every wrong answer tells you why.
Usa las pistas cuando las necesites. Cada respuesta incorrecta te dice por qué.
- A histogram shows these frequencies: 0–4: 3 players, 5–9: 8 players, 10–14: 12 players, 15–19: 5 players. How many players are represented in total?
- 12
- 15
- 20
- 28
- In a histogram, what does the height of each bar represent?
- The frequency (count) of data in that interval
- The average of the data in that interval
- The range of the interval
- The median of the data
- How is a histogram different from a regular bar graph?
- Histogram bars touch (no gaps) because the intervals are continuous ranges
- There is no difference
- Histograms have more bars than bar graphs
- Bar graphs show numbers and histograms show words

On Your OwnPor tu cuenta
Tables, mistakes to find, and problems with a few steps.
Tablas, errores por encontrar y problemas de varios pasos.
- Fill in the table
- A histogram of test scores shows: 50–59: 2, 60–69: 5, 70–79: 10, 80–89: 8, 90–99: 3. Which interval has the most students?
- 60–69 with 5 students
- 70–79 with 10 students
- 80–89 with 8 students
- 90–99 with 3 students
- Match each term to its description.
- What is the best next move?
- Draw one separate bar for each score, with gaps between them.
- Count how many scores fall in each interval.
- Make each bar as tall as the first number in its interval.
- Make the intervals different widths so the bars come out even.

- Does the histogram support the coach's claim?
- No — most players take 0–2 shots
- No — the data is skewed right
- Yes — 18 of 23 players cluster in the middle intervals
- You cannot tell from a histogram
