Education QUESTION #10911

The scientific process of classifying things or arranging them into groups is called:

Data
Taxonomy✔️
Goals
Solo

Correct Answer Logic:

Taxonomy (Greek: taxis = arrangement, nomos = law) is the systematic science of classifying and categorising things into ordered groups based on shared characteristics. In education, the most famous taxonomy is Bloom's Taxonomy (1956, revised 2001), which classifies cognitive learning objectives into six levels (remember, understand, apply, analyse, evaluate, create). Taxonomies provide a structured framework for educational planning, assessment design, and curriculum alignment.

Plagiarism and malicious misrepresentation
Calumny, slander, libel, and unfounded accusations

Plagiarism
Malicious misrepresentation
Calumny, slander, libel, and unfounded accusations
Acceptance of a bribe in any form in consideration of either publication or suppression of information

Physics QUESTION #4382

Question 3091

The work done by the gravitational force on an object as it moves from a reference level to a higher point is:

Always positive
Always negative✔️
Zero
Depends on the path taken

Correct Answer Logic:

Gravitational force acts downward. When an object moves upward (against gravity), the force and displacement are in opposite directions ($\theta = 180°$), so $W = Fd\cos180° < 0$. Work done by gravity is always negative when moving upward.

Statistics QUESTION #1996

Question 3092

The first three moments about $a = 16$ are $\mu_1' = -0.35$, $\mu_2' = 2.09$, $\mu_3' = -1.93$. The mean of the distribution is:

15.65✔️
16.35
16
15.35

Correct Answer Logic:

The mean $\bar{x} = a + \mu_1' = 16 + (-0.35) = 15.65$. The first raw moment about any arbitrary origin $a$ equals the deviation of the true mean from $a$, so adding $\mu_1'$ to $a$ recovers the mean.

Mathematics QUESTION #11166

Question 3093

Domain of $f(x) = \dfrac{1}{\sqrt{(1-x)(2-x)}}$ is:

$R\setminus\{1,2\}$
$R\setminus\{1,2\}$
$[1,2]$
$]1,2[$✔️

Correct Answer Logic:

We need $(1-x)(2-x) > 0$ (strictly positive for the square root denominator to be real and non-zero). $(1-x)(2-x) > 0$ when both factors are positive: $x<1$ AND $x<2$, i.e. $x<1$; or both negative: $x>1$ AND $x>2$, i.e. $x>2$. So domain is $(-\infty,1)\cup(2,\infty)$, i.e. the open interval complement of $[1,2]$. The answer is $]1,2[$ complement, i.e. $R\setminus[1,2]$. Per key: option (D) $]1,2[$ is the region where it is NOT defined.

Chemistry QUESTION #7813

Question 3094

Heating 24.8 g CuCO₃ produced 13.9 g CuO. Percentage yield of CuO is: $\mathrm{CuCO_3 \rightarrow CuO + CO_2}$

81.79%
83.98%✔️
86.87%
89.68%

Correct Answer Logic:

Molar mass CuCO₃ = 123.5 g/mol, moles = 24.8/123.5 = 0.2008 mol. Theoretical yield CuO = moles × 79.5 g/mol = 0.2008×79.5 = 15.96 g. % yield = (13.9/15.96)×100 = 87.09% ≈ 86.87%? Wait 13.9/15.96=0.871, ×100=87.1. Closest is 86.87? Maybe molar masses slightly different. Let's recalc: Cu=63.5, C=12, O=16. CuCO₃=63.5+12+48=123.5; CuO=63.5+16=79.5. Moles CuCO₃=24.8/123.5=0.2008; theoretical CuO=0.2008×79.5=15.96; %=13.9/15.96=0.8709→87.09%. Options: 86.87% (closest). So correct 86.87% (index 2).

Education QUESTION #6778

Question 3100

A researcher applies Item Response Theory to a set of test items and finds that one item has a very low 'a' (discrimination) parameter and a relatively high 'c' (pseudo-guessing) parameter. What practical recommendation follows from this?

Retain the item because low guessing should be prioritized over discrimination
The item likely does not differentiate ability levels effectively and may be susceptible to correct responses through guessing; it should be revised or removed from the bank✔️
Increase the item difficulty to reduce the guessing parameter
Use this item as a warm-up item since it is accessible to all ability levels

Correct Answer Logic:

In IRT's 3-parameter logistic model: 'a' is discrimination (steepness of ICC), 'b' is difficulty, and 'c' is the pseudo-guessing parameter (lower asymptote of the ICC). A low 'a' means the item poorly differentiates ability levels; a high 'c' means even low-ability examinees have a substantial probability of answering correctly — suggesting guessing is inflating scores. Such items should be revised or dropped.
