Click a question to see the answer.

1. Is =T.TEST volatile?

A. Yes
B. No ✓
C. —
D. No

Explanation: T.TEST is not volatile.

2. What is the type of argument “array1” in =T.TEST?

A. Array ✓
B. Text
C. Number
D. Mixed

Explanation: Type of “array1” is “Array”.

3. What usually causes #VALUE! in =T.TEST?

A. اگر tails مقداری غیر از ۱ یا ۲ باشد، تابع T.TEST خطای #NUM! را برمی‌گرداند.
B. Only works in old versions
C. If tails or type is nonnumeric, T.TEST returns the #VALUE! error value. ✓
D. Text is always ignored

Explanation: If tails or type is nonnumeric, T.TEST returns the #VALUE! error value. — Fix: برای tails و type مقدار عددی وارد کنید.

4. Which use case fits =T.TEST?

A. Descriptive Statistics
B. Probability & Hypothesis Testing ✓
C. Error Handling
D. Daily Tasks

Explanation: Use case “Probability & Hypothesis Testing” fits T.TEST.

5. Which statement about =T.TEST is correct?

A. Only works in old versions
B. Requires add-in
C. The tails and type arguments are truncated to integers. ✓
D. T.TEST uses the data in array1 and array2 to compute a non-negative t-statistic. If tails=1, T.TEST returns the probability of a higher value of the t-statistic under the assumption that array1 and array2 are samples from populations with the same mean. The value returned by T.TEST when tails=2 is double that returned when tails=1 and corresponds to the probability of a higher absolute value of the t-statistic under the “same population means” assumption.

Explanation: Correct: The tails and type arguments are truncated to integers.

6. Does =T.TEST return a dynamic array?

A. No ✓
B. Yes
C. —
D. No

Explanation: T.TEST does not spill.

7. What is the output type of =T.TEST?

A. Array
B. Value
C. Mixed
D. Number ✓

Explanation: Output is “Number”.

D. AVERAGE ✓

Explanation: “AVERAGE” is related to T.TEST.

9. Which is the correct syntax of =T.TEST?

A. =T.TEST(array1,array2,tails,type) ✓
B. T.TEST(array1,array2,tails,type)
C. =AVERAGE(array1,array2,tails,type)
D. =T.TEST(array1,array2,tails,type, 0)

Explanation: Correct syntax: =T.TEST(array1,array2,tails,type)

10. In =T.TEST, which is argument #1?

A. type
