Sample Size Calculation

2023
Knowledge of the sample size is the first requirement to conduct random sampling or an experiment. The sample size is the total number of units, observations, or groups (in some cases) used to get the data to estimate a population parameter. As the name suggests, the sample size is that of the sample drawn from the population and differs from the population size. The sample size for the given experiment or sampling effort is fundamental to any study design. Sample size decides the number of...

Investment includes business spending on capital goods and changes in inventories.Economists distinguish between planned investment and actual investment. Planned investment is what businesses intend to add to capital goods and inventories. Actual investment reflects the investment that businesses actually make.Businesses spend on capital goods such as trucks and computers. While investment in capital like machinery is always a deliberate, planned action, the second component of investment -...

The Anchoring-and-Adjustment Heuristic

2020
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the $2,000...

Adjusting Entries

2025
In accounting, a business's economic activities are segmented into designated time intervals, typically monthly, quarterly, or annually, known as accounting periods. This segmentation facilitates consistent tracking, summarization, and reporting of financial data, enabling stakeholders to accurately evaluate a company's performance and financial position. Companies must incorporate adjusting entries at the close of each period to ensure that financial reports conform to the accrual basis of...

Adjusting a Traverse

In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...
FAQs
The scale factor comes from comparing a known represented length with its corresponding real-world length. Expressing that relationship as a ratio creates a multiplier for converting other measurements from the drawing, image, or model. Once the ratio is established, applying it consistently allows each related dimension to be interpreted on the same scale.
Consistent units prevent the scale ratio from mixing unlike quantities, such as centimeters in a drawing and meters in the actual object. Before calculating, measurements should be converted into compatible units or the conversion should be included explicitly. This preserves the meaning of the scale factor and makes the resulting dimensions suitable for comparison or design checking.
The operation depends on how the scale factor is written. If the factor represents actual length divided by represented length, multiplying a drawing measurement gives the corresponding actual dimension. If the relationship is written in the reverse direction, division may be appropriate. Identifying which quantity belongs in the numerator prevents reversing the intended conversion.
A uniform scale factor changes every corresponding length by the same ratio, so the relationships among the object’s dimensions remain unchanged. For example, applying one consistent factor to length and width preserves their comparison while enlarging or reducing the representation. This proportional consistency supports reliable interpretation of technical drawings, models, and scientific images.
First, identify a labeled scale or a known corresponding measurement. Next, express the scale as a ratio with compatible units, measure the relevant feature, and apply the ratio using multiplication or division as appropriate. Finally, state the result with its unit and check whether it is consistent with the representation and the other calculated dimensions.
In maps, it converts represented distances into real-world distances. Architectural and engineering plans use it to interpret dimensions and verify whether a design corresponds to intended measurements. Scientific images and models can also be compared quantitatively when their scale is known. These applications turn visual representations into measurements that support estimation, comparison, and clear communication.
