Pokemon are fictional creatures which can be befriended, caught and trained by pokemon trainers. There are many different pokemon, and some pokemon can evolve into new pokemon, making them stronger. Each pokemon has a total of 6 stats, a height and weight, and a typing. For example, bulbasaur is a grass type pokemon, weighs 6.9kg and is 0.7m tall, bulbasaur has 45 hp and 49 attack. In this project we will compare the different stats of pokemon and how the generation they are from the the typing they have affect these stats.

There are currently nine generations of pokemon, each generation is typically released with a new video game, and comes from a specific region in the pokemon world. Let’s compare the different pokemon generations.

From the graph it seems like the earlier generations in general had more pokemon, with gen 5 introducing the most amount of pokemon with 156. The newest generation, gen 9, has added a substantial amount of new pokemon compared to the previous couple of generations with 120.

Dragon pokemon are known to be some of the larger pokemon, so let’s compare their height and weight to see who’s the largest pokemon

Seems like the pokemon Eternatus is the largest dragon type pokemon, and also an outlier. after removing it, let’s see if the size of a pokemon correlates to its hp stat.

Looking at the general trend of the graph, it seems that hp does scale with height and weight, with some exceptions being rayquaza, and regidrago, which are special cases since they are legendary pokemon.

In the pokemon video games, the speed stat is one of the most important stats in battling. If a pokemon has a higher speed stat than its opponent, it will get to move first, so generally it is good to have an above average speed.

Electric type pokemon tend to be some of the fastest pokemon, so let’s look at the spread of electric pokemon

Looking at the previous box plots, the data suggests that electric type pokemon do tend to be faster than other pokemon. With the median for electric pokemon being 11 points higher, and the upper quartile box being larger and the fastest pokemon, regieleki, having the highest speed stat of any pokemon at 200.

“Power Creep” is a term used in gaming that refers to the gradual increase in power of newer content. In pokemon, this would mean that pokemon from newer generations would be relatively better than pokemon from older generations. To test if this is true, we will perform a t test comparing the total stat count of pokemon from genertation 1 and generation 9.

## 
##  Welch Two Sample t-test
## 
## data:  total by Generation
## t = -3.7146, df = 234.87, p-value = 0.0002544
## alternative hypothesis: true difference in means between group 1 and group 9 is not equal to 0
## 95 percent confidence interval:
##  -76.13506 -23.36351
## sample estimates:
## mean in group 1 mean in group 9 
##        407.6424        457.3917

The results from the t test indicate that power creep is present as, on average, pokemon from generation 9 have a higher total stat count than pokemon from generation 1, rejecting the null hypothesis.

We have looked at the many stats that pokemon have, based on their typing and when they were introduced. The pokemon franchise is ever evolving, and between the complexity of the video and card games, and just the fun designs of the pokemon themselves, brings together people of all ages.
