Which term describes a sub-collection of elements drawn from a larger group to gain information?

Sample. A sample is a smaller, manageable portion of a population that is used to collect data and make inferences about the whole group.

Which of the following is an example of categorical data?

Eye color. Categorical data consists of non-numerical labels or names, such as eye color, whereas height and test scores are numerical data types.

What measure of central tendency is found by calculating the average of a set of data?

Mean. The mean is calculated by adding all the values in a data set together and then dividing by the total number of values present.

In a set of ordered data, what is the middle value called?

Median. The median is the middle value in a data set when all the numbers are arranged in numerical order from least to greatest.

Which measure of central tendency identifies the value that appears most frequently in a data set?

Mode. The mode is the value that occurs with the highest frequency in a data set; a set can have one, multiple, or no modes.

What is the difference between the highest and lowest values in a data set?

Range. The range is a measure of variability calculated by subtracting the minimum value from the maximum value in a given set of data.

What type of data is represented by values like height or test scores?

Numerical. Numerical data consists of values that are numbers, which allows for mathematical operations like finding the mean or range of the set.

If a probability is near 0, what does this indicate about the event?

It is unlikely. Probability is measured between 0 and 1; a value near 0 indicates that the event is very unlikely to occur in a random trial.

Which sampling method tends to produce representative samples for valid inferences?

Random sampling. Random sampling ensures that every element has an equal chance of being selected, which helps create a sample that represents the population well.

Hosted byBalancedSofiaBright & encouragingBright, warm English with encouraging lift

This pack is a shareable medium-level check on grade 7 statistics. Built for educators, L&D teams, and anyone running a review session who doesn't want a dry slide deck or a paper quiz.

Each question runs on a 20-second timer, with answer reveals voiced by Sofia. Sofia makes every fact feel like a discovery — bright, enthusiastic, genuinely curious. Total run time is about 5 minutes for 10 questions.

The pack covers Data collection basics, Measures of central tendency, Numerical vs categorical data, Understanding probability, Sampling methods, and Variability and range. Actual question text is kept off the lander so the first run doubles as a genuine pre-/post-test, not a review of the questions you already saw.

No accounts, no installs — participants open the link on any device and play. The results screen shows each player's score and streak, which is enough for a quick debrief without exporting data. All in English.
