Explore structured statistics & data science courses, solved problems, simulations and Python activities.
In this project you look at the highest temperature on each of 30 days. You show it in a table and a graph, find the centre, the spread and the chances, and write a short report with a limit. The code boxes only need Run and a few changed numbers.
In this short course you find the probability of an event by counting, check it with a simulation, and find the chance of two things happening together. You learn why a short run of tosses can mislead and a long run does not. The code boxes only need Run and a few changed numbers.
In this short course you find the range, the quartiles and the interquartile range, draw a box plot, and find the standard deviation step by step. You learn which measure of spread to use, and what happens to it when every value changes. The code boxes only need Run and a few changed numbers.
In this short course you find the mean, the median and the mode of a list of numbers, see why one extreme value can mislead the mean, and learn which average to use for which question. The code boxes only need Run and a few changed numbers.
Counting the answers is the first step. In this short course you build frequency tables, draw bar charts, pie charts, histograms and line graphs, choose the right graph for the data, and spot a graph that tells a false story.
In this short course you look at a table of data, sort data into its kinds, and learn how to ask fair questions and choose a fair sample. The code boxes only need Run and a few changed numbers, so you do not need to know Python.
These are part of our upcoming paid plans.
Real survey data is never tidy. In this project you clean a class survey, compare two groups with the mean and the median, and write a short honest report. It uses only what you learned in the first three chapters. The code boxes only need Run and a few changed numbers.
