How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: What is the mode of the data set $4, 4, 4, 4, 7, 7, 9$?

Answer: $4$. $4$ appears four times, far exceeding $7$ (twice) and $9$ (once).

Flashcard 2: What is the mode of the data set $1.5, 2.0, 1.5, 3.0$?

Answer: $1.5$. $1.5$ appears twice, while $2.0$ and $3.0$ each appear once.

Flashcard 3: What is the mode of a data set?

Answer: The value that occurs most often in the data set. The mode identifies the most frequently appearing value, providing insight into the central tendency of categorical or discrete data.

Flashcard 4: What does it mean if a data set has no mode?

Answer: No value occurs more often than all others. When all values appear with equal frequency, typically once, no single value stands out as occurring most often.

Flashcard 5: What does it mean if a data set is bimodal?

Answer: It has exactly $2$ values tied for greatest frequency. Bimodal datasets feature two distinct values sharing the highest frequency, indicating two peaks in the data distribution.

Flashcard 6: What is the mode of the data set $3, 5, 5, 7, 9$?

Answer: $5$. $5$ appears twice, more frequently than any other value in the set.

Flashcard 7: What is the mode of the data set $11, 12, 13, 11, 14, 15, 16$?

Answer: $11$. $11$ appears twice, more frequently than any other value, each appearing once.

Flashcard 8: What is the mode of the data set $2, 4, 6, 8$?

Answer: No mode. All values appear exactly once, resulting in equal frequencies and thus no mode.

Flashcard 9: What is the mode of the data set $10, 10, 10, 8, 8, 6$?

Answer: $10$. $10$ appears three times, exceeding the frequencies of $8$ (twice) and $6$ (once).

Flashcard 10: What is the mode of the data set $0, 0, 1, 1, 1, 2$?

Answer: $1$. $1$ appears three times, more than $0$ (twice) and $2$ (once).

Flashcard 11: What is the mode of the data set $2, 2, 2, 3, 3, 4, 4, 4$?

Answer: $2$ and $4$. $2$ and $4$ each appear three times, tying for the highest frequency over $3$ (twice).

Flashcard 12: What is the mode of the data set $3, 3, 2, 2, 1, 1, 0$?

Answer: $1$, $2$, and $3$. $1$, $2$, and $3$ each appear twice, sharing the maximum frequency, while $0$ appears once.

Flashcard 13: What is the mode of the data set $6, 6, 5, 5, 4, 4$?

Answer: $4$, $5$, and $6$. $4$, $5$, and $6$ each appear twice, tying for the highest frequency.

Flashcard 14: What is the mode of the data set $\frac{1}{2}, \frac{1}{3}, \frac{1}{2}, \frac{1}{4}$?

Answer: $\frac{1}{2}$. $\frac{1}{2}$ appears twice, exceeding the single appearances of $\frac{1}{3}$ and $\frac{1}{4}$.

Flashcard 15: What is the mode of the data set $12, 11, 12, 13, 11, 12$?

Answer: $12$. $12$ appears three times, more than $11$ (twice) and $13$ (once).

Flashcard 16: Which value is the mode if $8$ occurs $3$ times, $9$ occurs $3$ times, and $10$ occurs $1$ time?

Answer: $8$ and $9$. $8$ and $9$ both appear $3$ times, tying for the maximum frequency over $10$'s $1$.

Flashcard 17: What is the mode of the data set $5, 1, 5, 2, 3, 5, 2$?

Answer: $5$. $5$ appears three times, more than $2$ (twice) and $1$ or $3$ (once each).

Flashcard 18: What is the mode of the data set $7, 8, 9, 7, 8, 9, 10$?

Answer: $7$, $8$, and $9$. $7$, $8$, and $9$ each appear twice, sharing the maximum frequency over $10$ (once).

Flashcard 19: What is the mode of the data set $100, 90, 100, 80, 90, 70$?

Answer: $90$ and $100$. $90$ and $100$ each appear twice, tying for the highest frequency over $80$ and $70$ (once each).

Flashcard 20: What is the mode of the data set $9, 7, 9, 7, 8, 7, 9$?

Answer: $7$ and $9$. Both $7$ and $9$ appear three times, tying for the highest frequency, while $8$ appears once.

Flashcard 21: Identify the mode of the data set $14, 15, 14, 16, 17, 14, 15$.

Answer: $14$. $14$ appears three times, exceeding $15$ (twice) and $16$ or $17$ (once each).

Flashcard 22: What is the mode of the data set $1, 2, 2, 3, 3, 4$?

Answer: $2$ and $3$. Both $2$ and $3$ appear twice, tying for the highest frequency in the set.

Flashcard 23: Which value is the mode if $2$ occurs $5$ times and $3$ occurs $4$ times?

Answer: $2$. $2$ has the highest frequency of $5$, compared to $3$'s $4$.

Flashcard 24: What does it mean if a data set is multimodal?

Answer: It has more than $2$ values tied for greatest frequency. Multimodal datasets exhibit three or more values with the same maximum frequency, reflecting multiple peaks in the distribution.

Flashcard 25: What is the mode of the data set $-1, -1, -2, -2, -2, 0$?

Answer: $-2$. $-2$ appears three times, surpassing $-1$ (twice) and $0$ (once).
