fredwill1357: This method can be tedious but that's what I use to receive cash from my foreign clients. If the person uses Western Union, supply him/her with your correct details as you have in your local bank. The money will be wired to you and you'll be given a tracking ID. Enter any bank that uses Western Union and give them the ID and cash out the money (dollar), locate any BDC closer to you and change the money to Naira. I don't deal with gift cards but it is hard to imaging you getting less than half of what you are supposed to get. 8 Likes |

noob03saibot: Principal Component Analysis is used to reduce the dimensionality of a dataset which contains a lot of variables. PCA allows you to bring down this number of variables by creating new representative variables that are not correlated in vector space and can be used in your analysis. With PCA, you are able to reduce the dimension of your dataset while minimizing information loss at the same time. |

Series Two Objectives At the end of this series, you should be able to: 1. Know what measure of central tendency is 2. How to describe your data using measure of central tendency 3. Know the appropriate measure to use in describing your data What are measures of central tendency? A measure of central tendency is a value that attempts to describe a set of data by identifying the central position within that set of data. Therefore, measures of central tendency are also referred to as measures of central location. Because they try to give us the summary of our data, measure of central tendency are also referred to as summary statistics. The most commonly encountered measure of central tendency is the mean (also called average), but this is not the only measure as we also have the mode and the median. Now let us look at what different measure tells us about our data. Mean The mean is the average of all the values in the dataset; it is calculated by summing up the values which is then divided by the number of the values. For example, if we collect the age of five boys as 9, 12, 7, 8, 10, the mean is the addition of these values (46) divided by the number of the boys (i.e 5) which gives us 9.2. The mean therefore describes the most common value in your data. This, however, is rarely the actual value observed in your data. Despite being the most common measure of central tendency, mean has two major drawbacks; (a) Susceptibility to outliers: Outliers are unusually large or small numerical values compared to the rest of the data set. For example, if the wages of developers is a tech company is 30k, 37k, 45k, 16k, 25k and 100k. The mean salary for this six staff will be 169.9k. However, careful inspection of the raw data will reveal that the mean value might not be the best measure to describe this data as most wages fall in the 30 - 45k range. The mean is being affected by two small and large values. In this situation, using a better measure of central tendency (such as the median)should be considered. (b) Skewness: When the dataset is heavily tailed to one side, the mean does not best describe the data as it loses its ability to provide the best central location for the data because the skewed data is dragging it away from the typical value. Median When our data is arranged in order of magnitude, the median is the middle score. It is less affected by skewed data and outliers. Mode The mode is the most frequent score in our data set. Let's see how we can get these measures using Python import statistics # for calculating our mean, median and mode Challenge: implement mean, median and mode in Python without using any library 3 Likes |

Harkstetunz: If len(sys.argv)is returning 1, it means you only have one argument in the program which is the filename (or the executable). sys.argvreturns a list with the first element being the filename followed by other arguments in the program. We'll be able to make significant contributions if you could share the whole code.

Series 1: Variables Objectives At the end of this series, you should be able to: 1. Define variables 2. Know different types of variables 3. Know the difference between variables and constants 4. Know what explanatory and response variables are What are variables? Variables are characteristics that are measured and can take on different values. In other words, something that varies between cases or observations. In contrast, a constant always remains unchanged for all observations in a research study. Let's take on few examples to understand this better. Example 1: A researcher wants to study the relationship between the educational qualification and the level of awareness of COVID-19 protocols in a sample of 100 male passengers. The variables are; (a) Educational qualification which could range from none to tertiary education (b) Awareness level which could be defined using Likert scale Also, we have 100 observations/cases, biological sex (male) is a constant. Types of Variable 1. Categorical variable: they are names or labels (e.g gender, race, state) with no logical order or with a logical order but inconsistent differences between groups (e.g., rankings). Categorical variables are also known as qualitative variables. 2. Numerical variables: they are variables with quantifiable measurements e.g height, weight, and average rainfall. They are also known as quantitative variables. Example 2: A team of clinical researchers want to study the relationship between age and obesity. Weight here can be quantified either in Kilogram or other units, it is therefore a quantitative(numerical) variable while gender is a category (or label) and is therefore a categorical (qualitative) variable. Variables can as well be grouped into explanatory (independent) and response (dependent) variables. In such a case, we are trying to use one variable to predict or explain the difference in another variable. Example 3: A researcher wants to predict nutritional status using racial origin. He then takes a random sample of 100 individuals of distinct race. The explanatory variable here is race and the response variable is nutritional status. The next series is going to be on how to describe different variables. 4 Likes |

Topics to cover We are going to cover several topics that border on descriptive and inferential statistics. Descripive statisitcis 1. Types of variables 2. Measure of central tendency 3. Measure of spread 3. Graphs and plots Inferential statistics 1. Hypothesis testing 2. Parametric assumptions 3. Sample inference (one sample and two samples) 4. Chi-square test of independence 5. One-Way ANOVA 6. Linear regression and correlation 7. Logistic regression Tools to use The tremendous improvement in technology has made it possible to implement almost any statistical concept using different tools. In light of this, you can follow this series using any tool(s) of your choice, but personally, I'll be combining a number of Python libraries together with Microsoft Excel.

Programming / Applied Statistics For Data Analysis/science by ibromodzi: 8:38am On Dec 11, 2020 |
Data analysis involves inspecting data to gain insights that inform conclusions and impact decision making. The theoretical framework of data analysis is strongly built on statistics and logical techniques (mathematics) while the implementation of its concepts heavily relies on computer science. These three fields are what gave birth to data analysis/ science and as such, this tutorial series is focused on highlighting the important statistical concepts that are employed in different data analytics tasks with implementation in statistical tools of choice of the readers. I have come in contact with a sizeable number of people who are just finding their way into data science and I've noticed that most people use the top-down approach whereby they first concentrate on using different statistical tools while paying little or no attention to the underlining theoretical concepts upon which these principles are built. The implication of this is that many start to question the reason why they got into data science in the first place because they find it somehow difficult to pinpoint the kind of problems they are solving with these tools or the exact questions they are trying to answer with the data. if you find yourself in this category, don't be infuriated, I was once in the same dilemma, just take a deep breath, grab your tools, and follow along in this series. 3 Likes 2 Shares |
