A retailer is one of the most popular and effective distribution channels. Retailers include supermarkets, department stores, specialty stores and big-box retailers. Today marketers working with retailers can put their products in physical stores, online stores or both.

**Why AC distribution is preferred than DC distribution?**

AC power can easily be step-up or step down with the help of a transformer which is not possible in the case of DC power. Electricity that is coming to our homes is AC because it comes from a far away power generation plant so **the loss of energy during transmission is very less in the case of AC power than DC power**.

**What is an efficient distribution management?**

Effective distribution management involves **selling your product while assuring sufficient stocks in channels while managing promotions in those channels and their varying requirements**.

**What is the efficiency of a distribution?**

Distributive efficiency is **when the consumer goods in an economy are distributed so that each unit is consumed by the individual who values that unit most highly compared to all other individuals**.

## Why is normal distribution the best?

Answer. The first advantage of the normal distribution is that **it is symmetric and bell-shaped**. This shape is useful because it can be used to describe many populations, from classroom grades to heights and weights.

One reason the normal distribution is important is that **many psychological and educational variables are distributed approximately normally**. Measures of reading ability, introversion, job satisfaction, and memory are among the many psychological variables approximately normally distributed.

**What is better than normal distribution?**

**T-distributions** have a greater chance for extreme values than normal distributions, and as a result have fatter tails. The t-distribution is the basis for computing t-tests in statistics.

Reliability refers to the consistency of a measure. Psychologists consider three types of consistency: **over time (test-retest reliability), across items (internal consistency), and across different researchers (inter-rater reliability)**.

**How do you get a reliable distribution system?**

Reliability of the electric power system can be increased by either **shortening the duration of the interruptions of the power supply or by lowering the frequency by which interruptions occur**. The probability that a component in the system will fail is generally increased when the number of components rises.

The cost factor of channel efficiency is calculated on a number of business-specific factors, such as: Marketing budget. Advertising budget.

**Why AC is more reliable than DC?**

AC can be transmitted across long distances without much energy loss, unlike DC. The power loss during transmission in AC is less when compared to DC.

**Is DC more efficient than AC?**

**What is the efficiency of a DC?**

The efficiency of a DC generator is defined as **the ratio of mechanical input power to the output electrical power**.

**What is the efficiency of a DC circuit?**

An ideal DC-DC converter would have **100%** efficiency, operate over arbitrary input- and output-voltage ranges, and supply arbitrary currents to the load.

**Why is efficient distribution important?**

An efficient distribution network **allows for wider customer reach** because it should ideally enhance the speed at which products reach the end consumer and opens up opportunities to reach other geographic areas.

## Is normal distribution perfect?

**A normal distribution comes with a perfectly symmetrical shape**. This means that the distribution curve can be divided in the middle to produce two equal halves. The symmetric shape occurs when one-half of the observations fall on each side of the curve.

**Why is the normal distribution so common?**

The reason it's so common is because **many phenomena have typical or 'mean' values due to their underlying causes (such as genetics), plus random variation caused by a host of chance effects**.

**What is normal distribution vs standard normal distribution?**

The difference between a normal distribution and standard normal distribution is that **a normal distribution can take on any value as its mean and standard deviation.** **On the other hand, a standard normal distribution has always the fixed mean and standard deviation**.

All kinds of variables in natural and social sciences are normally or approximately normally distributed. **Height, birth weight, reading ability, job satisfaction, or SAT scores** are just a few examples of such variables.

**What are the advantages of Poisson distribution?**

The advantage of the Poisson distribution, of course, is that **if N is large you need only know p to determine the approximate distribution of events**. With the binomial distribution you also need to know N.

**What is true about the T distribution?**

Like the normal distribution, **the t-distribution has a smooth shape**. Like the normal distribution, the t-distribution is symmetric. If you think about folding it in half at the mean, each side will be the same. Like a standard normal distribution (or z-distribution), the t-distribution has a mean of zero.

**Should I use t-distribution or normal distribution?**

You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: **If σ is not known, then using t-distribution is correct.** **If σ is known, then using the normal distribution is correct**.

**What is the best type of reliability?**

**Inter-rater reliability** is one of the best ways to estimate reliability when your measure is an observation. However, it requires multiple raters or observers. As an alternative, you could look at the correlation of ratings of the same single observer repeated on two different occasions.

**What are 2 examples of reliability?**

When a measurement is consistent it's reliable. But of course, reliability doesn't mean your outcome will be the same, it just means it will be in the same range. For example, **if you scored 95% on a test the first time and the next you score, 96%, your results are reliable**.

**What are the 4 types of reliability?**

**What is a reliable system?**

Reliability can be defined as **the probability that a system will produce correct outputs up to some given time t**. Reliability is enhanced by features that help to avoid, detect and repair hardware faults. A reliable system does not silently continue and deliver results that include uncorrected corrupted data.

**What makes a reliable system?**

Reliable systems are **those that can continuously perform their core functions without service disruptions, errors, or significant reductions in performance**.

**What is an example of reliability of a system?**

Reliability is complementary to probability of failure, i.e. R(t) = 1 –F(t) , orR(t) = 1 –Π[1 −Rj(t)] . For example, **if two components are arranged in parallel, each with reliability R _{1} = R _{2} = 0.9, that is, F _{1} = F _{2} = 0.1, the resultant probability of failure is F = 0.1 × 0.1 = 0.01**.
