Measures of central tendency summarize data using mean, median, and mode, helping to understand data distribution.

• Mean: The average of a set of numbers, useful in calculating average test scores in education.

• Median: The middle value in a sorted list, often used in income data to avoid skew from outliers.

• Mode: The most frequently occurring value, applicable in determining the most common diagnosis in a medical study.

• Example: In sports, the mean score of players can indicate ov...read more

Ordinal, nominal, interval, and ratio scales are types of measurement scales used in statistics to categorize and quantify data.

• Nominal Scale: Categorizes data without a specific order (e.g., blood type, gender).

• Ordinal Scale: Ranks data in a specific order but does not quantify the difference between ranks (e.g., pain levels: mild, moderate, severe).

• Interval Scale: Measures data with meaningful intervals but no true zero point (e.g., temperature in Celsius).

• Ratio Scale: Simi...read more

Normal distribution is crucial in statistics for modeling real-world phenomena and facilitating inferential statistics.

• Central Limit Theorem: Many statistical methods rely on the assumption of normality; as sample sizes increase, the distribution of sample means approaches normality.

• Standard Scores: Normal distribution allows for the calculation of z-scores, which help in understanding how far a data point is from the mean in terms of standard deviations.

• Statistical Inference...read more

Capital budgeting is the process of planning and evaluating long-term investments in assets and projects.

• It involves analyzing potential investments and determining which ones will provide the best return on investment

• Factors such as cash flow, risk, and opportunity cost are considered in the decision-making process

• Examples include building a new factory, purchasing equipment, or launching a new product line

Factorial 0 is defined as 1 by convention.

• Factorial is the product of all positive integers up to a given number.

• 0! is defined as 1 by convention, as it simplifies many mathematical expressions.

• Example: 5! = 5 x 4 x 3 x 2 x 1 = 120, 0! = 1

The value of sin 45 degree is 0.70710678118

• Sin 45 degree is a trigonometric function that represents the ratio of the length of the side opposite to the angle of 45 degrees to the length of the hypotenuse in a right-angled triangle

• The value of sin 45 degree can be calculated using a calculator or by using the Pythagorean theorem

• The exact value of sin 45 degree is √2/2 which is approximately equal to 0.70710678118
