from import when # changing the values in the education column # changing the values in the marriage column spark_df_done = None spark_df_done. You can do this by using a method called. Similarly, the category "0" looks small, so let's throw it in with the "Other" values. We can go ahead and throw them into the "Other" category since it's already operating as a catchall here. It looks like there are barely any of the 0 and 5 categories. import seaborn as sns import matplotlib.pyplot as plt # plotting the categories for education After doing so, come up with a strategy for accounting for the extra values. Create bar plots of the variables 'EDUCATION' and 'MARRIAGE' to see how many of the undefined values there are. Let's look at some visualizations of each of these to determine just how many of them there are. it looks like we have some extraneous values in each of our categories.

How can we use light and colour to change the way something looks? What happens if we mix different colours together or if we block colours of light? Lead the investigation as we explore the wonders of our colourful world.In the previous lesson, you saw how to manipulate data with Spark DataFrames as well as create machine learning models. What will you decide to mix together? Lights, colour, action! Use your science skills to see what changes might happen. Mixing two or more chemicals together can sometimes lead to surprising outcomes. Have you ever been zapped by a door handle or had your hair stand up on a trampoline? What materials will you select to create static electricity and how can you use it to make something move? Mix master Which substances will you choose to go head-to-head in the float tank? Join us at the Science Bar as we explore the mysteries of density and discover together what features make substances sink or float? Snap, crackle, watt? How do different materials compare? What can you do to affect the rate of change? Will it float? Test our your ideas for changing solids into liquids. Things are heating up at the Science Bar. What would a marshmallow look like in the vacuum of outer space? Use your science skills to predict and explore how changing air pressure can lead to observable changes in a variety of objects. Going down hillĭo all things tumble in the same way when moving down a slope? Select different materials and choose the angle of the slope as you investigate how we can change the way things move. The Science Bar program changes daily and program topics are listed on the digital screen near the Science Bar. Science Bar is included as part of your SparkLab ticket. These drop-in Science Bar programs are short, intimate experiences that are tailored to the audience. Get up close with live science experiments and demonstrations where the audience get to ask questions, predict outcomes and direct part of the investigation.
