d. x must be manipulated

history effect

events external to the experiment that affect the responses of the people involved in the experiment

experiments-procedure

- decide on your treatmnets what are you trying to test? how many factors? what will you do if you have the information -design the experiment design -recruit participants and run the experiment -analyze the experiment data

the 41 shades of blue test at google

-a team at google couldnt decide between two blue -they test 41 shades between each blue -showing each one to 1% of their visitors to see which ones perform better

machine learning

-an application of artificial intelligence that allows systems to automatically learn and improve without actually being programmed to do so -machine learning focuses on creating systems that can access data and automatically apply themselves -as the data system gets more and more experience, the better it will become at analyzing data

AB tests

-are field experiments in the digital marketing context making use of big data -AB tests are often run as part of a live, real marketing effort -AB are often automated to be adaptive -are rooted in experimental design -however, often: AB test oftne test two or more competing messages without necessarily seeking to understand why, experiments test hypothesis-> seek to understand outcomes and reasons

before and after

-as the name suggests, with after only experimental designs measures the independent variable are only taken after the experimental subjects have been exposed to the independent variable - the before and after design is based upon the after only design, in that the effect of the independent variable, if any, is established by observing differences between the value of the dependent variables before and after the experiment

Lets pretend we work at facebook

-ask question: how can be stop more people from deactivating their facebook -do research: the reason why people use facebook is that their friends are on facebook -hypothesis: if you remind people about their friends who are being left behind, we will lover the deactivation rate

The Scientific Method

-ask questions -hypothesis -research -analyze data -conclusion

causal inference

-causal inference is the formal name for cause and effect interpretations of research methods like experiments -experiments yield higher causal inference with other analyses such as regression yield lower causal inference (ie they are more correlational)

comparison visualizations

-comparison charts are used to compare the magnitude of values to each other and can be used to easily find the lowest and highest values in the data -it can also be used to compare current values vs old to see if the values are increasing or decreasing - common questions are "what products sell best" and "how are our sales compared to last year"

composition visualizations

-composition charts are used to see how a part compares to the whole and how a total value can be divided into shares -a composition charts shows the relative value, but some charts can also be used to show the absolute difference -the difference is between looking at the percentage of total and value of total -common questions are "how big part of the market do we have in a region" or "what areas is our budget divided into"

examples of machine learning

-computational finance, for credit scoring and algorithmic trading -image processing and computer vision, for face recognition, motion detection and object detection -production, for price forecasting -automative, aerospace, and manufacturing, for predictive maintenance -natural language processing for voice interaction

distribution visualization

-distribution charts are used to see how quantitative values are distributed along an axis from lowest to highest -looking at the shape of the data a user can identify characteristics such as the range of values, central tendency, shape and outliers -it can be used to answer questions such as "number of customers per age group" or "how many days late are our payments"

4 cornerstones of a data visualization

-distribution of a single variable -relationship between two variables -composition of a single or multiple variables -comparison between different categories/individuals

data visualization

-each time you map data to visualization, the key thing you need to consider is: what are you trying to show the user? it isnt a question of what looks pretty -learn about the right type of chart: you want a chart that demonstrates value and achieves its purpose in an easily recognizable way

interactive design

-introducing more than one factor typically yields rich insights -moderator variable: changes the way the independent variable affects the dependent variable -interaction: test of one factor across all levels of another factor

segmentation and target with AB testing

-many software systems allow marketers to analyze the success of options during the exploration stage of AB testing across different segments for applying the results intelligently across segments in the exploitation stage -this method could also be useful for determining which segments to target, especially if one option tested is more profitable than the other

after only

-measures of the independent variable are only taken after the experimental subjects have been exposed to the independent variable -this is a common approach in advertising research where a sample of target customers are interviewed following exposure to an advertisement and their recall of the product, brand or sales features is measured

lab experiment cons

-more artificial -physical environment -small data -more control over other influences

AB testing pros

-more realistic -digital environment -big data -less control over other influences

AI marketing: content personalization

-organisms amplifying group intelligence by forming flocks, schools, shoals, colonies and swarms (eg, bees, birds, fish, ants) -research shows: groups outperform most individuals in decision making and prediction regardless of expertise -most surveys, focus groups, and polls fail to recognize this social aspect of decision making

Applied (most common)

-perform single task extremely well -run automated and repetitive tasks -does not involve decision making -ex: netflix, spotify, self driving cars

what are the tools to deliver those three marketing principles

-product -price -place -promotion

artificial applied intellegence

-refers to systems that are designed to work on specific tasks, such as trading stocks or controlling an autonomous vehicle -is most common

artificial general intelligence

-refers to systems that can handle any task -is more complicated since the systems are dealing with an infinite number of tasks rather than focusing on just one -is less common

relationship visualization

-relationship charts are used to see the relationship between the data and can be used to find correlations, outliers, and clusters of data -common quesions are "is there a correlation between advertising spend and sales for our products" or "how does expenses and income vary per region and whats the deviation"

causal inference in simple terms

-requirements for causal statement x->y 1. x must occur before y 2. there must be evidence of association between x and y 3. control of other causal factors -(1) is typically manipulated (2) can be assessed by the data (3) is typically done by randomizing , matching or blocking -product advertisement on tv-> choice of product purchased

2 categories of machine learning

-supervised -unsupervised

simple design

-the most basic experimental design has a single factor -a factor is an independent variable (referred to as x) that may affect the dependent variable (often referred to as y) -IV means the marketing input we are interested in changing -dv is outcome variable

Labratory vs field experiment (AB test)

-validity: a field experiment tends to have higher external validity but a smaller internal validity -exposure: by doing a field study, you may provide information to competitors or adversely affect the marketplace

marketing channels for AB testing

-website promotion (copy, images, video) -email campaign (messaging, subject line) -social media ads (messaging, images, video) -digital retailing ( messaging, pricing) -text coupons (messaging, price promotion) -mobile ads (messaging, iamges)

supervised machine learning

-where you ahve input variables (x) and output variable (y) and you use an algorithm to learn the mapping function from the input to the output (y) for

unsupervised machine learning

-where you only have input data (x) and no corresponding output variables -the goal for unsupervised learning is to model the underlying structure or distribution in the data in order to learn more about the data -algorithms are left to their own devices to discover and present the interesting structure in the data

AI marketing: tool platforms

1. albert -used for autonomous media buying -buying digital media on behalf of clients -analyzes, manages, and optimizes paid advertising campaigns 2. frank -pay per click -uses machine learning to find best paid advertising channels depending on specific audience

three things needed for causal inference

1. x must occur before y 2. there must be evidence that x is associated with y 3. other causal factors are ruled out
