2. 4- Data analysis

2.1. Descriptive statistics

2.1.1. Definition: Descriptive statistics make it possible to enumerate and describe a population in an exhaustive way (eg success rate).

2.1.1.1. We distinguish between

2.1.1.1.1. Univariate statistics

2.1.1.1.2. Bivariate statistics

2.1.1.1.3. Multivariate statistics

2.1.2. A-Univariate statistics

2.1.2.1. Categorical variable

2.1.2.1.1. You can create frequency tables for that type of variables (see slide 34)

2.1.2.1.2. Graphical representation: we use bar charts or Pie charts. See slide 43

2.1.2.2. Scale variable

2.1.2.2.1. You can compute

2.1.2.2.2. Graphical representation:

2.1.3. B-Bivariate statistics

2.1.3.1. Categorical variable

2.1.3.1.1. We can create a contingency table (2 categorical variables) -- see slide 58

2.1.3.1.2. Graphical representation: you can use bar plots

2.1.3.2. Crossing a scale variable and categorical variable (aka grouping variable) - slide p65

2.1.3.3. Crossing two scale variables

2.1.3.3.1. Variables

2.1.3.3.2. We can observe

2.1.3.3.3. Graphical representation: we use a scatter plot (correlation plot) to represent the relationship between two variables. See slide 68

2.2. Inferential statistics

2.2.1. Definition: It is about estimating the numerical characteristics of a population from the observation of one of its parts (a sample) thanks to the inference.

2.2.1.1. We need inference to express with a certain degree of confidence that (a difference, or relation) we observed within our sample will probably be observed in the population if we conduct a census.

2.2.2. We use hypothesis testing to infer if what we observed in our sample can be generalized to the population with some level of confidence

2.2.2.1. All the inferential tests work with the same logic

2.2.2.1.1. A hypothesis is a quantitative statement about the characteristics of a population.

2.2.2.1.2. We distinguish H0 or null hypothesis and its alternative hypothesis called H1

2.2.2.1.3. To decide whether or not to reject H0 (hence its "plausible" character), we examine the statistical significance of the test: p-value. --- See slides 80-83

2.2.2.2. What types of tests exist ? (toolbox)

2.2.2.2.1. We distinguish between parametric vs non parametric tests

2.2.2.2.2. How to select the right test ? (see slide 85 and 90) for details

3.1.5.1.2. No ambiguous words

3.1.5.1.3. Identification questions (for example: gender, age, etc) should be at the end of your questionnaire. The only exception is if they are used as filter questions (like a quota, or to select the respondents you want to survey)

3.1.5.2. Modalities

3.1.5.2.1. Must be exclusive

3.1.5.2.2. A homogeneous number of modalities for Likert scale (5 or 7, etc.. )

3.2. Selecting the sample

3.2.1. Vocabulary

3.2.1.1. Reference population

3.2.1.1.1. “The set of objects having the desired information to meet the objectives of a study”.

3.2.1.2. Sampling frame

3.2.1.2.1. is a concrete representation of the elements of the target population (For example the list that contains all the reference population)

3.2.1.3. A sample

3.2.1.3.1. "is a subset of elements extracted from a population they are supposed to represent"

3.2.1.4. Sampling unit

3.2.1.4.1. It is an "object, or entity containing an object, that will be selected for inclusion in the sample"(individual? Household? state? etc.)

3.2.1.5. Unit of analysis

3.2.1.5.1. It is an "object, or entity containing an object, that will be selected for the analysis“

3.2.1.6. We distinguish between

3.2.1.6.1. The census

3.2.1.6.2. The sample

3.2.2. What errors to avoid when sampling? There are 2 types of possible errors

3.2.2.1. Sampling error

3.2.2.1.1. the fact of forgetting one or more important observations. which make the sample unrepresentative, such as not taking Renault-Nissan into account in a study of the French automotive industry.

3.2.2.2. The non sampling error

3.2.2.2.1. it is, by contrast, any error that is not due to sampling (For example: a response error, input, etc.). It's an error that results during data collection, causing the data to differ from the true values.

3.2.3. There are basically 2 sampling approaches (to select a sample)

3.2.3.1. Probabilistic methods (we randomly select respondents). Each member of the population has a known non-zero probability of being selected. YOU SHOULD GENERALLY HAVE A SAMPLING FRAME (LIST THAT CONTAINS ALL THE POPULATION)

3.2.3.1.1. 1- Simple random survey (sampling)

3.2.3.1.2. 2- Random systematic survey (sampling)

3.2.3.1.3. 3- Stratified sampling: A stratum is a subset of the population that share at least one common characteristic. Examples of stratums might be males and females, or managers and non-managers. The researcher first identifies the relevant stratums and their actual representation in the population. Random sampling is then used to select a sufficient number of subjects from each stratum. "Sufficient" refers to a sample size large enough for us to be reasonably confident that the stratum represents the population. It can be Proportional or Non proportional

3.2.3.1.4. 4- Cluster survey (sampling)

3.2.3.2. Non probabilistic methods (A.k.a. empirical methods). Members are selected from the population in some nonrandom manner (quotas, convenience, etc )

3.2.3.2.1. Convenience Sampling

3.2.3.2.2. Judgment (purposive) sampling

3.2.3.2.3. Referral /Snowball Sampling

3.2.3.2.4. Quota Sampling

3.3. Sample size

3.3.1. To compute the sample size we need three elements:

3.3.1.1. E: desired margin of error (precision). If you want to augment your precision, you will have the augment the sample size and thus the cost.

3.3.1.1.1. Having a margin of +/-3% means that if you have a result of 60% in your sample, it means that the real result in the population is probably (see Z below) between 57% and 63%

3.3.1.2. Zc is the critical value from the table of probabilities of the standard normal distribution for the desired confidence level (generally Z=1.96 for 95% confidence)

3.3.1.2.1. You will express your results with a confidence of 95% that your estimations for the reference population are correct based on what you observed in your sample (60%), so the real score is somewhere between {57%-63%} and we are 95% confident about that result.

3.3.1.3. p (for a percentage) or σ (for an average). p is the proportion of a phenomenon in the case of an estimated percent (for example, we want to estimate the % of people that vote republicans). Meanwhile, σ is the standard deviation in the case of estimating an average (for example, we want to estimate the monthly leisure budget of our respondents)

3.3.1.3.1. If you don't have 'p' you have 2 choices

3.3.2. Some statistical concepts

3.3.2.1. The standard deviation

3.3.2.1.1. The Standard Deviation is a measure of how spread out numbers are. We can say about it that it's the average deviation from the average (or mean). Standard deviation is calculated as the square root of variance

3.3.2.2. Variance

3.3.2.2.1. The average of the squared differences from the Mean. You can look on blackboard for the file: Computing variance and standard deviation.xlsx

3.3.2.3. The Z score

3.3.2.3.1. Z score indicates how many standard deviations an element is from the average. The formula is (x-average/(standard deviation)) -- see slides - P34

3.3.2.4. The normal distribution

3.3.2.4.1. The normal distribution (Or Gaussian) is a very common distribution for quantitative values. The normal distribution is the most important distribution in statistics because it fits many natural and social phenomena. For example, errors in measurements, blood pressure, marks on a test, etc. The normal distribution describes how the values of a variable are distributed.

3.3.2.4.2. Addendum: there are many other statistical distributions (t distribution, binomial, etc), but generally, when we have a sample size bigger than 30 observations, we start to observe that they tend to converge towards a normal distribution. This is called the central limit theorem.
