The seven basic statistical methods serve to summarize, analyze, and interpret data effectively. They help in identifying patterns, trends, and relationships within data sets, enabling informed decision-making. By employing these methods, researchers can draw meaningful conclusions, assess variability, and make predictions, ultimately enhancing the understanding of complex information.

How is it that business researchers can justify treating a seven point Likert scale as interval?
Business researchers often justify treating a seven-point Likert scale as interval data because the scale provides an ordered range of responses that are equidistant, allowing for meaningful mathematical operations. They assume that the differences between scale points represent equal intervals of the underlying variable being measured, facilitating the use of parametric statistical techniques. While strictly speaking, Likert scales are ordinal, the interval treatment is common in practice due to its practical utility in analyzing survey data. This justification is further supported by the central limit theorem, which allows for the approximation of distributions under certain conditions, making parametric tests applicable.
What is the probability of obtaining exactly six heads in seven flips of a coin given that at least one is a head?
The requirement that one coin is a head is superfluous and does not matter. The simplified question is "what is the probability of obtaining exactly six heads in seven flips of a coin?"... There are 128 permutations (27) of seven coins, or seven flips of one coin. Of these, there are seven permutations where there are exactly six heads, i.e. where there is only one tail. The probability, then, of tossing six heads in seven coin tosses is 7 in 128, or 0.0546875.
Seven hundredths as a decimal?
0.07
A coin is flipped seven times What is the probability that the outcome is other than all seven heads?
That's the same as the total probability (1) minus the probability of seven heads. So: 1 - (1/2)7 = 127/128
What is the most likely outcome when tossing two dice?
Seven - there are more ways to make seven than there are to make any other number.

When conducting a experiment does the number of trials affect the results?
The number of trials does not affect the result as each individual trial or experiment yields its own result caused by random small variations in the techniques used. What is affected is the conclusion derived from pooling all the individual results for the same type of trial and analysing the value obtained by statistical methods. It is generally reckoned that at least seven trials are required for the purpose of statistics and the analysis is commonly expressed as the Mean (average value) and Standard Deviation, (a number that reflects the extent of the variation between the individual trials). However, different statistical methods are used for analysing different types of data, the commonest reflecting the difference between parametric (the variation is the same on both sides of the mean) and non-parametric (The spread of variation is greater on one side of the mean than the other). Obviously a considerable number of individual trials is required to be able to make a valid distinction between the two.
