Corrected version:

The chart provides an overview of people using various social media networks in Canada. It reflects on two consecutive years, 2014 and 2015.

Explanation: 

In this sentence, the word "network" should be pluralized because it is referring to multiple social media platforms. The word "about" is not the most appropriate choice in this context. "On" is a better word to use when discussing a specific time period.

Improved version:

The chart provides an overview of the usage of various social media networks in Canada over a two-year period, from 2014 to 2015. 

Corrected version:

The green bar stands for 2014, while the blue represents 2015.

Explanation: 

The word "reflex" is not the correct term to use in this context. "Represents" is a more appropriate word to convey the intended meaning.

Improved version:

The green bar represents data from 2014, while the blue bar represents data from 2015.

Corrected version:

The percentage of people who do not use any website is 22% in 2014 and decreased by one percent in 2015.

Explanation: 

The word "native" does not accurately describe the group being referred to in this sentence. Using "percentage" or "proportion" would better convey the intended meaning.

Improved version:

It can be clearly observed that the percentage of individuals who do not use any website decreased by one percent, from 22% in 2014 to 21% in 2015. 

Corrected version:

However, the percentage of people who used a single website in the year 2014 is 36%, and in 2015 it decreased to 28%.

Explanation: 

The phrase "in year" is not grammatically correct. Using "in the year" or "in 2014" would provide the correct phrasing.

Improved version:

Conversely, the percentage of people who used a single website decreased from 36% in 2014 to 28% in 2015.

Corrected version:

The chart depicts that the number of citizens who use dual applications hovered around a quarter of the population.

Explanation: 

The word "depics" is not the correct spelling. "Depicts" is the correct word to use in this context.

Improved version:

The chart also reveals that approximately a quarter of the population in Canada used dual applications, with this proportion remaining relatively stable throughout the two-year period.

Corrected version:

The analysis of data reveals that the number of single app users is more than others.

Explanation: 

The phrase "app user" should be pluralized to "app users" because it is referring to multiple individuals.

Improved version:

Furthermore, the analysis of the data highlights that the number of single app users was higher than any other category. 

Corrected version:

Moreover, throughout the period of 2014 and 2015, the number of users who used three applications increased by one third.

Explanation: 

The phrase "is increased" is not grammatically correct. Instead, using "increased" provides the correct verb tense.

Improved version:

Moreover, there was a significant increase in the number of users who utilized three applications, with a one-third increase observed between 2014 and 2015.

Corrected version:

The provided tabular chart depicts that users across three categories increased in greater proportion.

Explanation: 

The phrase "three sides users" does not accurately convey the intended meaning. Using "users across three categories" or "users from three different groups" provides clearer phrasing.

Improved version:

The provided tabular chart demonstrates that users across three different categories experienced a greater increase in proportion.

Corrected version:

The figure for users of four sites drew a rise of 3%.

Explanation: 

The phrase "sites users" should be rephrased as "users of four sites" to provide clearer and more accurate wording.

Improved version:

Interestingly, the figure for users of four sites experienced a rise of 3% during the two-year period.

Corrected version:

Across six distinct sessions, the number of users on five sites has been recorded as fewer, whereas they increased twofold in one year.

Explanation: 

"Lesser" is not the correct term to use in this context. "Fewer" is the appropriate word to use when referring to a smaller number. Additionally, "two folds" should be replaced with "twofold" to convey the intended meaning of doubling in quantity.

Improved version:

In contrast, the number of users on five sites was recorded as fewer across six distinct sessions, but this group experienced a twofold increase in one year.
